compound.xsd is missing types for some elements

[ilitzroth]

Describe the bug
When I run the xsd program (https://www.codesynthesis.com/products/xsd/) on the compound.xsd that is generated by doxygen it complains of the following missing type attributes:

To Reproduce
run the xsd program on the compound.xsd in the repo under
templates/xml

Expected behavior
No warnings, i.e. the types of all the elements is specified.

Version
1.11.0, but also tested on the repo.

Additional context
I'm trying to write a convertor from the xml produced by doxygen to texinfo.

That is the fix I applied locally :-)

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).

This issue was previously marked 'fixed but not released',
which means it should be fixed in doxygen version 1.12.0.
