XSD question (same attributes, different elements...)

[Gooseman]

Hi

Just getting into XSD and have some questions:

If I have several different elements that all have identical attibutes, what is the best way of conveying that in the XSD?

Is there a way of defining that an attribute must be either xs:ID OR a set of predefined lables (ie something like xs:ID | "specific_lable_1" | "specific_lable_2" ?

The XSD schema I am writing is fully defined, yet some of the attributes for the various elements are yet to be implemented. What's the best way of adding a "not yet implemented" flag to these attributes?

Thanks!
