Re: <include> with XSV (web-version)

Jeff,

I've done some more testing and with your suggestions I finally managed to
validate my examples by adding:

<!DOCTYPE xsd:schema PUBLIC "-//W3C//DTD XMLSCHEMA 200102//EN"
"http://www.w3.org/2001/XMLSchema.dtd" [
  <!ENTITY % s ':xsd'>
  <!ENTITY % p 'xsd:'>
]>

to my Fields.xsd schema [1]. BTW, I also found an error in my first schema where
I had the attribute declaration:

<xsd:attribute name="tag" use="fixed" value="15A"/>

This is the old declaration from the CR and the new declaration in PR should be:

<xsd:attribute name="tag" fixed="15A"/>

I agree that this is frustrating. I tried (like you) to use the prefix xs:
instead of xsd: but that doesn't work. I guess this means that you have to
specify a DOCTYPE declaration if you want to use the online version of XSV.

Cheers,
