union operator and predicates in XSLT patterns

Hi; just a quick query for my own understanding.  Apologies if I've gotten the wrong list.

I wanted to use both a union and operator in an XLST template, i.e. match="(div1|div2)[not(@role)]" (simplified).

This is, I think, equivalent in XPath 2.0 as "/*//(div1|div2)[not(@role)]", which I would expect to follow the rule for patterns in XSLT (the node $N matches pattern PAT if $N is a member of expression "root($N)//(PAT)".  However, this shows as invalid.

Can someone explain this to me? :)
