Re: using xs:choice inside xs:all

Hi Mahesh,

You cannot have xs:choice inside of xs:all.
I think it may be possible to write the content model to match your 
requirements with choice and sequence but that may be complex.
If Schematron does not scare you :) then you may use Schematron embedded 
rules to enforce your constraints and relax the content model in the XML 
Schema to a choice between your possible elements.

Best Regards,
George
