RE: xslt 2. index-of, nodes

No, I was wrong, it's not a Saxon bug.

You are doing

<xsl:for-each-group select="rec[mu/loc]">

but there is only one "rec" element in your data, so of course there is
only one group and only one item in that group.

I suspect you meant to do select="rec/mu[loc]", or something similar.
