[xml] 'XML Schema - "union" patch'

[Kasimier Buchcik <kbuchcik 4commerce de>]

Hi,

You may find attached a patch that tries to implement the handling of 
the "union" XML Schema item. Note that validation of "union" is not very 
performant, since the "memberTypes" attributes has to be evaluated every 
time a validation occurs. This should not be a final implementation of 
"union", but I see no other simple way of implementing it. Feel free to 
modify it (especially the dictionary stuff during validation, since I 
did know better).


Greetings,

Kasimier
