RE: [docbook-apps] DocBook XMLschema in Visual Studio.Net

["Wills, Robert" <Robert dot Wills at sts dot co dot uk>]

We had some success using "XMLSpy" to 'flatten' various flavours of DocBook
DTD and then convert them into a usable XML Schema. Other tools may be able
to do the same (maybe even VS.NET?). You could try manually adding a target
namespace to the generated XSD if VS.NET can't handle elements defined in
the 'no-namespace' namespace (this seems an odd restriction, though). You'll
need to make appropriate mods to the stylesheets if you're using XSLT.

After some experimentation we've reverted to DTD for simple edit-time
validation because of better support in current generation editors. In
particular I would check how/if you plan to use XML entities in your docs as
with several editors these appear to be unusable in conjunction with an XSD.
As far as I can see the XML Schema spec doesn't actually outlaw them, but
I've not seen anyone recommending mixing the two.

Rob.

That's the lack of VS.NET.

XML schema for DocBook doesn't define target namespace. I think that
VS.NET can't validate against schemas without target namespace. This
might be problem.

it be possible to switch to the DocBook DTD for processing or are there
compatibility issues between the two?

I think that XML Schema is still experimental but dependency on XML
schema should not affect processing tools as they usually didn't rely on
validation. 

XML schema for DocBook is available in CVS repository at
docbook.sourceforge.net.
