Re: Problems with latest Xerces/Xalan Xerces -- FIXED!!!

Okay, I finally fixed the problem involving validating DTDs when
namespaces are turned on. PLEASE check out the latest from CVS
and pound on it to make sure that I didn't hose something else
in the process!

Just found a bug in XMLValidator that will barf on prefixed attributes other
than "xmlns:..", "xml:...", such as "foo:attr1", even if it is already
defined in DTD.
 fix is already in CVS.

Yeah, my previous fix only worked on DTD documents that didn't use
namespaces at all. I just checked in some code before posting this
message that looks like it fixes all cases of using DTD validation
with namespaces.

I tried your sample file and it seems to validate fine. Let me
know if you find any more problems.

Thanks for working on this.  I checked out the latest sources and got a
different error.  This is with SAX "validation" true and "namespaces"
the default value of true.  The error I got was:

"Element type "foo:root" must be declared."

It seems that the element is already declared in the DTD.  Below is my
simple test document.

-Edwin

<?xml version="1.0"?>

<!DOCTYPE foo:root [

<!ELEMENT foo:root (foo:element1, element2)>
<!ATTLIST foo:root
    xmlns:foo CDATA #REQUIRED
>

<!ELEMENT foo:element1 (#PCDATA)>

<!ELEMENT element2 (#PCDATA)>
]>

<foo:root xmlns:foo="http://www.foo.com/foo">
    <foo:element1>test</foo:element1>
    <element2>test2</element2>
</foo:root>

Okay, a little more work needs to be done. The namespace issue
with DTDs works fine as long as you aren't adding the namespace
prefixes to the element/attribute names in the DTD. So now I 
have to get that working, too. 

Also, I think that there might be some work needed to verify
that xml:lang and xml:space still work in these situations.
