I think that using the same method as you'd use in XSLT 1.0 would
work:

  count(preceding::loc[@hl = $context/@hl and
                       @side = $context/@side and
                       @pos = $context/@pos]) + 1

That's right. The arguments to index-of() are atomised to atomic
values, so you're getting the index of the <loc> element with the same
typed value as the <loc> element you're looking at.

Of course there might be other, better, methods depending on how
you're processing the <loc> elements. For example, perhaps you could
use XSLT 2.0's grouping mechanism to process all the <loc> elements in
the group at once, and then just use position().

Cheers,

Jeni
