W3C Schema Question

Dear All,

I have a situation in which I need to anticipate the possibility of 2 different datatypes in a single XML element (I'm thinking xsi:type right now, but I'll continue).  I have an element that can either be a date, or an asterisk.  The date or asterisk will always appear in the same element - i.e. there are not separate elements for these.  So we can have:

<MyElement>2002-02-02</MyElement>

in one XML document, and then:

<MyElement>*</MyElement>

in another.

Is there an efficient way to handle this within a single schema, ensuring that invalid dates are detected?

Kind Regards,
