in
conjunction
with
other
XHTML

in
XHTML

enables
a
more
robust
accessibility

than
is
presently
possible.

This
document
contains
a
single
module
designed
to
be
used
to
help
make
XHTML-family
markup
languages
more
effective
at
supporting
the
needs
of
the
Accessibility
Community.
It
has
been
developed
in
conjunction
with
the
W3C's
Web
Accessibility
Initiative
and
other
interested
parties.
It
provides
a
generic
mechanism
for
defining
the
relationship
between
document
components
and
well-known
accessibility
vocabularies.
This
section
is
normative
.
The
keywords
"MUST",
"MUST
NOT",
"REQUIRED",
"SHALL",
"SHALL
NOT",
"SHOULD",
"RECOMMENDED",
"MAY",
and
"OPTIONAL"
in
this
document
are
to
be
interpreted
as
described
in
[
RFC2119
].
Note
that
all
examples
in
this
document
are
informative,
and
are
not
meant
to
be
interpreted
as
normative
requirements.
XHTML
Access
is
not
a
stand-alone
document
type.
It
is
intended
to
be
integrated
into
other
XHTML
Family
Markup
Languages.
A
conforming
XHTML
Access
document
is
a
document
that
requires
only
the
facilities
described
as
mandatory
in
this
specification
and
the
facilities
described
as
mandatory
in
its
host
language.
Such
a
document
must
meet
all
the
following
criteria:
-
The
document
MUST
conform
to
the
constraints
expressed
in
its
host
language
implementation.
-
If
the
host
language
is
not
in
the
XHTML
namespace,
and
the
host
language
does
not
incorporate
this
module
into
its
own
namespace,
then
the
document
MUST
contain
an
xmlns:
declaration
for
the
XHTML
Access
namespace
[
XMLNAMES
]
.
The
namespace
for
XHTML
Access
Module
is
defined
to
be
http://www.w3.org/1999/xhtml
.
An
example
start
tag
of
a
root
element
might
look
like:
Example
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" >
When
XHTML
Access
is
included
in
a
host
language,
all
of
the
facilities
required
in
this
specification
MUST
be
included
in
the
host
language.
In
addition,
the
element
defined
in
this
specification
MUST
be
included
in
the
content
model
of
the
host
language.
The
element
defined
in
this
specification
MAY
be
incorporated
into
the
namespace
of
the
host
language,
or
it
MAY
remain
in
the
XHTML
namespace.
Finally,
XHTML
Access
requires
the
availability
of
the
XHTML
Role
Attribute
Module
[
XHTMLROLE
]
and
of
the
Core
Attribute
Collection
as
defined
in
XHTML
Modularization
[
XHTMLMOD
].
A
conforming
user
agent
MUST
support
all
of
the
features
required
in
this
specification.
This
section
is
normative
.
This
module
defines
the
access
element.

The
access
element
assigns
an
accessibility
mapping
to
elements
within
a
document.
Actuating
the
mapping
results
in
the
element
gaining
focus
(either
the
document
focus
or
an
inspection
focus,
as
determined
by
the
user
agent),
and,
if
set
by
the
author
and
permitted
by
the
user's
settings,
in
one
or
more
other
events
being
activated.
An
access
element
must
have
either
a
targetrole
or
a
targetid
attribute
specified.
If
neither
a
targetrole
nor
a
targetid
attribute
are
specified,
the
user
agent
MUST
NOT
define
a
mapping
nor
deliver
any
events.
Attributes
The
activate
attribute
indicates
whether
a
target
element
should
be
activated
or
not
once
it
obtains
focus.
The
default
value
for
this
attribute
is
"no",
indicating
that
the
element
will
not
be
"activated".
User
agents
MUST
provide
mechanisms
for
overriding
the
author
setting
with
user-specified
settings
in
order
to
ensure
that
the
act
of
moving
content
focus
does
not
cause
the
user
agent
to
take
any
further
action
(as
per
Checkpoint
9.5
of
UAAG
1.0
[
UAAG1
]).
User
agents
MUST
provide
keyboard
mechanisms
for
"activating"
any
event
associated
with
the
focused
element
(as
per
Checkpoint
1.2
of
UAAG
1.0).
User
agents
SHOULD
make
available
the
list
of
events
associated
with
the
focused
element
(as
per
Checkpoint
9.6
of
UAAG
1.0).
This
attribute
assigns
a
key
mapping
to
an
access
shortcut.
An
access
key
is
a
single
character
from
the
document
character
set.
Triggering
the
access
key
defined
in
an
access
element
moves
focus
from
its
current
position
to
the
next
element
in
navigation
order
that
has
one
of
the
referenced
role
or
id
values
(see
activate
for
information
on
how
the
element
may
be
activated).
Note
that
it
is
possible
to
deliver
alternate
events
via
[
XMLEVENTS
].
The
invocation
of
access
keys
depends
on
the
implementation.
For
instance,
on
some
systems
one
may
have
to
press
an
"alt"
or
"cmd"
key
in
addition
to
the
access
key.
User
agents
MUST
provide
mechanisms
for
overriding
the
author
setting
with
user-specified
settings
in
order
to
ensure
that
the
act
of
moving
content
focus
does
not
cause
the
user
agent
to
take
any
further
action,
as
required
by
UAAG
1.0,
Checkpoint
9.5.
[
UAAG1
]
The
character
assigned
to
a
key,
and
its
relationship
to
a
role
or
id
attribute
SHOULD
be
treated
as
an
author
suggestion.
User
agents
MAY
override
any
key
assignment
(e.g.,
if
an
assignment
interferes
with
the
operation
of
the
user
interface
of
the
user
agent,
if
the
key
is
not
available
on
a
device,
if
a
key
is
used
by
the
operating
environment).
User
agents
MUST
also
allow
users
to
override
author
assigned
keys
with
their
own
key
assignments
(see
Checkpoint
11.3
of
UAAG
1.0).
If
a
user
chooses
to
change
the
key
binding,
the
resultant
user-defined
remapping
SHOULD
persist
across
sessions.
If
no
key
attribute
is
specified,
the
user
agent
SHOULD
assign
a
key
and
alert
the
user
to
the
key
mapping.
The
resultant
user
agent
assigned
key
mapping
SHOULD
persist.
The
rendering
of
access
keys
depends
on
the
user
agent.
We
recommend
that
authors
include
the
access
key
character
in
label
text
or
wherever
the
access
key
is
to
apply.
If
the
user
agent
can
recognize
that
the
currently
mapped
access
key
character
appears
in
the
label
text
of
the
element
to
which
it
is
mapped,
then
the
user
agent
may
render
the
character
in
such
a
way
as
to
emphasize
its
role
as
the
access
key
and
distinguish
it
from
other
characters
(e.g.,
by
underlining
it).
A
conforming
user
agent
SHOULD
also
provide
a
centralized
view
of
the
current
access
key
assignments
(see
Checkpoint
11.1
and
Checkpoint
11.2
of
UAAG
1.0).
The
targetid
attribute
specifies
one
or
more
IDREF
s
related
to
target
elements
for
the
associated
event
(i.e.,
the
node
to
which
the
event
should
be
delivered).
The
targetrole
attribute
specifies
a
space
separated
list
of
CURIE
s
[
CURIE
]
that
maps
to
an
element
with
a
role
attribute
with
the
same
value.
If
a
targetid
and
a
targetrole
are
both
specified
for
an
element,
the
targetid
attribute
value
must
take
precedence.
If
the
prefix
is
omitted
from
a
CURIE,
the
default
value
of
http://www.w3.org/1999/xhtml/vocab#
MUST
be
used.
Access
element
that
focuses
into
a
field
<access key="s"
title="Social Security Number"
targetrole="ss:number" />
Accessing
a
table
of
contents
<access key="c"
title="Table of Contents"
targetrole="toc" />
Access
that
moves
to
the
main
content
<access key="m"
title="Main content"
targetrole="main" />
Access
element
that
goes
to
a

<access key="u"

Access

with
no

key

<access title="Navigation bar"

of

defined
