Can choice appear 0 or more times?

Hi,

I'm trying to represent (a|b)*

My first inclination was to do it with a choice:

<xsd:choice minOccurs="0" maxOccurs="unbounded">
<xsd:element name="a" type="xsd:string"/>
<xsd:element name="b" type="xsd:string"/>
</xsd:choice>

Is this legal?

I have a complexType (derivedType) derived from a different complexType
(baseType). The derivedType adds a choice element like in the example
above. I'm trying to determine if it is legal to determine if our
software has a bug or not... Thanks for any responses!

Yes, and it means what you want.

Thanks. I have one more question... How would I determine the number of
choices and which choices they are using XPath...?
