• Current clone of Repository

This is a moving target so please specify the version used (though I can reproduce the problem with the current master, 1.9.8 (2777acd) and an empty project).

The message:

Group 'docTitleCmdGroup' from targetNamespace='' has invalid definition: Circular group reference.

It looks like the

  <xsd:group name="docCmdGroup">
    <xsd:choice>
      <xsd:group ref="docTitleCmdGroup"/>

so the group in the group or choice in choice gives some problems.

• what is the purpose of the the generation of the classes? Is it something similar to what is done for doxmlparser?

[davidcorbin-atmosera]

@albert-github - Thanks for the prompt response. First the easy part, I can confirm I am using 2777acd

As for "why", that is more complicated. I am looking to perform some analytics. Rather than attempting to parse source code, using the DoxyGen XML files seemed good (still does!), but then there was the choices in a .Net world of how to load them, and I was investingating XSD for strongly typed classes...

Not familiar with doxmlparse... will have to look that up.
I would love to discuss: david(dot)corbin(at)atmosera(dot)com.

I've just pushed a proposed patch, pull request #10196
(even though it is not really nice to copy the data)

[davidcorbin-atmosera]

Thanks. That gave me an idea (though I really wish MFST would update XSD to properly support Circular - and svcutil is not a great option either).

[albert-github]

Code has been integrated in master on GitHub (please don't close the issue as this will be done at the moment of an official release).
