Any API for required/optional from an XSD?

[Adam Flinton <adam.flinton@nhs.net>]

Dear All,

I need to interrogate/process an element within a xsd/schema & simply
ask "what are my required child nodes (elements & attributes)" & then
"what are my optional child nodes (elements & attributes)"

Is there an api (preferably java) or an XSLT sheet which would provide
this information?

TIA

Adam
