        (Woo! Looks like 
XML-DEV is back!)

        
Hi!

        I have a question. To 
illustrate it, take a look at this markup:

<document xmlns="http://www.example.com/document"
xmlns:sample="http://www.sample.com/sample">
        
<paragraph id="one">This is a sample 
paragraph.</paragraph>
        
<sample:text id="one">This is another sample 
paragraph.</sample:text>
</document>

        
Let's assume that the schema for the "document" said that the "id"
attribute 
on "paragraph" was is an ID (as in the attribute type).
Let's also assume 
that the schema for the "sample" said that the "id"
attribute on "text" is an 
ID.

        Should a validation tool 
flag an error (e.g. using two identical IDs
in one 
document)?

        I don't think it 
ought to (since it's one document, but two
different schemas), but I also 
think of namespace-qualified document
fragments as being islands in and unto 
themselves.

        Anybody got any 
ideas? And pointers to specifications that define
what ought to be happening 
here?

--->Ben
