Hi Yves, all, one further solution I could think of would be two "pointer" attributes: one is pointing to the "ref" attribute, the other to the external element: <its:rules version="2.0"> <its:qaErrorRule selector="//xlf:mrk[@type='itsqa']" errorInfoRefPointer="@ref" errorExternalInfoPointer="//itsqa:error[@id=substring-after($errorInfoRefPointer,'#')]/@info"/> xmlns:xlf="urn:oasis:names:tc:entity:xmlns:xml:catalog"/> </its:rules> We when could say that errorExternalInfoPointer MUST contain a variable that is called "errorInfoRefPointer" and is bound by the XPath expression in errorInfoRefPointer. This is also not very clean, but it removes the dependency on XPath 2.0. Phil, maybe this also helps to make the indirection clearer, let's also discuss this tomorrow.
