Re: [xml-dev] Any API for required/optional from an XSD?

[George Cristian Bina <george@oxygenxml.com>]

Take for instance a content model as simple as a choice between two 
elements:

a | b

Is a required?
Is b required?

All you know if that either a or be is required.

Take another example

a, b, a?

Is a required or optional?

There is no list of required elements, you can get however the required 
content model. For example if you have a content model like

(a | b), c?

then you can extract the required content model as

a | b

Best Regards,
George
