RE: [xsl] RE: Counting preceding elemets of similar node, but in different branch

["Michael Kay" <mike@xxxxxxxxxxxx>]

Using position() looks perfectly correct here if your xsl:apply-templates is
written the way you say it is. It wouldn't be correct however if you reach
the QUESTION elements indirectly via intermediate elements. Perhaps you need
to show a more complete stylesheet.

It might be safer however to use <xsl:number level="any"/>.
