A character is an atomic unit of text as
specified by ISO/IEC 10646 . Legal characters are tab, carriage
return, line feed, and the legal characters of Unicode and ISO/IEC
10646. The versions of these standards cited in were current at the
time this document was prepared. New characters may be added to
these standards by amendments or new editions. Consequently, XML
processors MUST accept any character in the range specified for
Char.

Glossary for this

Strings consist of a sequence of zero or
more characters, where a character is defined as in the XML
Recommendation [XML]. A single character in P3P thus corresponds to
a single Unicode abstract character with a single corresponding
Unicode scalar value (see [UNICODE]).

Glossary for this

A character is an atomic unit of text as
specified by ISO/IEC 10646 [E67](see also ). Legal characters are
tab, carriage return, line feed, and the legal [E35]graphic
characters of Unicode and ISO/IEC 10646. [E69]The versions of these
standards cited in were current at the time this document was
prepared. New characters may be added to these standards by
amendments or new editions. Consequently, XML processors must
accept any character in the range specified for Char. The use of
compatibility characters, as defined in section 6.8 of [E67](see
also D21 in section 3.6 of ), is discouraged.

the data. Refer to the Unicode specification [UNICODE] for more
information about character encodings. Refer to "Character Model

From Authoring Tool
Accessibility Guidelines 1.0 (2000-02-03) |
Glossary for this
source
As used in checkpoint 4.1, "check for" can
refer to three types of checking: In some instances, an authoring
tool will be able to check for accessibility problems
automatically. For example, checking for validity (checkpoint 2.2)
or testing whether an image is the only content of a link.In some
cases, the tool will be able to "suspect" or "guess" that there is
a problem, but will need confirmation from the author. For example,
in making sure that a sensible reading order is preserved a tool
can present a linearized version of a page to the author.In some
cases, a tool must rely mostly on the author, and can only ask the
author to check. For example, the tool may prompt the author to
verify that equivalent alternatives for multimedia are appropriate.
This is the minimal standard to be satisfied. Subtle, rather than
extensive, prompting is more likely to be effective in encouraging
the author to verify accessibility where it cannot be done
automatically.
