Re: [xml-dev] Polyglot XHTML5 Validator?

Thanks David

I have found two more bugs, and I think we need a couple of more
assertions, please.

Here is a Bug, should be false() instead of true().
<sch:pattern>
<sch:rule context="h:noscript">
<sch:assert test="true()" >noscript elements should not be used.</sch:assert>
</sch:rule>
</sch:pattern>

Here is a Bug, should be "h:" before meta.
<sch:pattern>
 <sch:rule context="meta[@charset]">
 <sch:assert test="lower-case(@charset)='utf-8'">If meta/@charset is
used, it must specify utf-8.</sch:assert>
</sch:rule>
</sch:pattern>

*** Here is an issue. I guess the following assertion is irrelevant
because & and > are picked up by well-formedness test when the
document to be validated is loaded?
<sch:pattern>
 <sch:rule context="h:script|h:style">
 <sch:assert test="not(matches(.,'[&lt;&amp;]'))" >script and style
should not use &amp; or &lt;</sch:assert>
 </sch:rule>
 </sch:pattern>

*** I feel that we need an assertion to test that the following meta
tag is not used. This is important because XSLT method="xhtml" inserts
it by default. The whole idea with polyglot markup is that we only
need to change the mime-type outside the document to serve it as HTML
or XHTML.
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

*** Also I think we need an assertion to test that only the 5 named
entity references in XML are used. HTML allows many more and the
polyglot schema has valid HTML5 as point of departure.

*** Also I think we need an assertion testing that document.write()
and document.writeln() are not used.

*** And a question (one more time) about the now corrected assertion:
<sch:pattern>
 <sch:rule context="h:textarea|h:pre">
<sch:assert test="not(matches(.,(:'^\s':)'^[&#10;&#13;]'))">textarea
and pre should not start with <!--white space-->newline</sch:assert>
</sch:rule>
 </sch:pattern>

Isn't it better to use the questionmark:
^[&#10;?&#13;]
