I think you might want to take a look at xsd:keyref which allows the making
of xpath constraints against elements as a reference to an xsd:key, there's
also xsd:unique but I don't think it offers anything like what you want.
anyway as a general rule people want to use xsd:appinfo for what you seem to
be suggesting
perhaps you might also be interested in using schematron instead of XML
Schema?http://www.ascc.net/xml/resource/schematron/schematron.html
there is also some work for including schematron inside of appinfo
