[opencms-dev] nested xml content

[Alexander Kandzior]

In order to nest XML content schemas, the nested element mut be in it's own
file that gets included by the first schema. Please see the demos in the
xmlcontent demo folder.

Please note that the XML content schemas must follow some very strict rules
on how they are written. This includes naming rules and strcuturing rules.
All this is required to give a decent runtime performance. OpenCms uses some
very slim classes to represent the XML schemas during runtime, and these
classes do support only a limited subset of all XML schema options. 

Best Regards,
Alex.
