the construct is legal in XSLT1, I try always to say explictly if I'm
using xslt2 draft (as xslt 1 is currently the official version)

It wasn't that anyone was _recommending it_ it was that the OP did it
anyway and you commented that it wasn't allowed, whereas in fact it is.

in XSLT 1 the parent of an attribute is an element, and
match="@foo[parent::bar]" is a legal XSLT1 match pattern.
