Subject Re: conditions in XML

XML stores content. There is no logic associated with the content in the XML
document. XSLT can be used to added conditional logic for elements to
indicate during a transformation of the XML document whether an element, and
various permutations of it's childern, parents siblings and such should be
included in the transformation.

I know it doesn't answer your question but the crux is that XML contains no
logic but XSLT in conjunction with XML content will do what I would guess
you are trying to do.
