LC-2374 Dominique Hazael-Massieux <dom@w3.org> (archived comment)
A quick comment after re-reading WARP at the invitation of Robin to DAP
[1]: I don’t think the notion of subdomain is well-defined; is w3.org a
subdomain of .org? is co a subdomain of co.uk? I assume they are in the
sense of the spec, but if that’s so, it doesn’t match the “street”
meaning of the word “subdomain”; this matters in particular in section 7
(rules for granting access), since this has an impact on how a user
agent decides to grant access to a network resource. Given that IP
addresses are allowed, the algorithm to determine if something is a
subdomain of another domain is as simple as looking to the last dot in
the authority component.

(kudos on the spec otherwise; I find it to be very crisp)

I gots me confused by the second sentence, maybe change to:

"Requests by an author to access network resources can be identified
by the presence of access
elements in the widget's configuration document."

It's confusing to talk about "interfaces" here, though I understand
you are talking about interfaces in general terms. I would prefer if
the spec just said:

"This specification defines conformance criteria that apply to a single
product: user agents."

And a "user agent" be defined as "a software application that
implements this specification and the [WIDGETS] specification and it's

i think you need to make it really clear that you've just defined the
"default policy" for a WUA. Please make it a sub-section or something.

P&C uses "Context in which this element is used:". It would be nice if
this one said the same thing :)

"that is requested" seems tautological... and makes the sentence read
funny (and not "ha ha" funny.)

I would rewrite:

Break here.

I'm really sorry, I'm having a hard time parsing the above sentence.
At first, I thought it was related to the sentence about "*". Can you
change the order of these sentences above. Also, the "*" value is
pretty important, maybe it deserves it's own sub-section even if it
just contains one short paragraph. i'm sure people will come back
asking for clarification once we go to CR as to how it's supposed to

It should be clear that "subdomains" and "domain" here refers to
components of RFC-such-and-such, right?

what does it means when I have:

<access domain="http://foo.bar.woo.com" subdomains="true"/>

Everything before "woo.com" is allowed, right? Maybe could be clear in
the spec for people like me :)

The above sentence doesn't tell me anything (that I can understand)
about the example. It be nice if it told me what I was looking at a
bit more. Maybe you need to break this up into multiple examples,
showing when it would be appropriate to use "*".

Instead of the fancy sentence above, why don't you just add a <widget
xmlns="..."> around the access elements?

> <access origin="http://dahut.example.com:4242"/>

Can you please move the above sentence above the table. First thing I
thought when I read the first para of this section was "when! when do
I need to do that?!?!?! when!!!" :)

Whoa, hang on. This whole section is not well introduced. Please add
some text at the start of this section integrating the whole thing.
For example, you could say that the section defines an algorithm that
needs to be integrated into the Steps for processing a widget user
agent. Then, make the addendum to Step 3. Follow that hooking into
Step 7.

i think the above should be above the sentence starting "For each..."

If you would be so kind, could you please add <p> around the text of
each bullet. It makes the algorithm easier to read.

rule for getting a single attribute needs link to P&C.

Broken links for various components (host, iuser, etc)... but you know
that already.

Just ignore the scheme? or ignore the element? I know you mean
"element", but I got confused for a few seconds.

"must ignore it" > "must ignore this element"

Typo: "Network Resources" or "a Network Resource"?

An example would be nice here, maybe a little venn diagram diagram
would help too :)

This is some tricky-ass algebra. You need some example here.
