[opencms-dev] schema recursion ....

[Ruben Malchow]

hi achim

well, in my case, this would be input for a custom selector widget that 
lets you select from items in a hierarchy. also, the actual depth is 
defined by what the user actually wants to put in there.

i __could__ make it a N-level hierarchy with a fixed N, but that's even 
more ugly than arbitrary recursion that _could_ get kind of awkward if 
the user really, really wants that.

i think the main point is that the content definition is only cached 
after it has been completely parsed (CmsXmlContentDefinition, line 753 
in v7.5.2). if it would be parsed before unmarshal goes into the 
contents of it, it would be fine ... i guess.
