[xep-support] More on <rx:page-index>: feature request

[Paul A. Hoadley]

Hello,

In my attempt to augment the DocBook XSL automatic index generation,
I've hit a problem that I don't think I can solve with rx:key and
rx:page-index.  The DocBook DTD allows for an <indexterm> within the
text to have a 'class' attribute which can specify 'startofrange' and
'endofrange'.  An element with the latter must also carry a 'startref'
attribute that points to the 'id' of its corresponding 'startofrange'.
The generated index will then contain a range of pages for an
indexterm spanning between the two elements.

I don't see how I can integrate this with the rx:key and rx:page-index
extensions -- putting an rx:key in the text at the start and end of
the range will just generate two single page references in the
rx:page-index.

Assuming it's not achievable (and I'd be happy to be proven wrong
there), would that be an easily implemented feature?  Perhaps an
rx:key, but also rx:startkey and rx:endkey attributes?  (This may be
naive -- overlapping ranges would be a problem, for one thing.)
