Rules based on attribute values...

jacob · July 4th, 2005, 12:03 PM

Is it possible through XML Schema Definitions to model e.g. that an attribute value can only be some specific value if another attribute has got another specific value? Say I have an XML document where these two nodes valid are present...

Code:

<task type="begin" action="establish" />
<task type="end" action="finalize" />

... then I will not allow...

Code:

<task type="begin" action="finalize" />

I am aware that I could do two seperate elements, but is there a way to model more constraints like this?

Hope you can help, Jacob.

I don't think this is possible using XML schemas.
