Out of interest, how does it work with the following:

/descendant::*[@foo = 'bar']

Also, what happens with regard to wildcards in template matches:

<xsl:template match="*[@foo = 'bar']">

<xsl:template match="*[@foo = 'something else']

Given some element, I would imagine you have to check for any direct
matches (the integer comparison) and if none are found, then go
through these one at a time?
