Summary: indexterm with duplicate sortas is missing from index

Initial Comment:
When two indexterms have the save value for their @sortas attribute, one of the indexterms will not appear in the index. The problem is that @sortas, if present, is treated as the primary for that element.  If two terms have the same primary, they are merged into a single index entry with multiple page numbers. But they need to be separate indexterms if their actual primary elements differ.

The solution is to use both @sortas and primary as the key in the indexterm xsl:index.  Then the entry will sort on the first part, but will be different from other indexterms with the same primary value.

Message:
I replaced the old indexterm entity declarations used for sorting and
grouping:

<!ENTITY primary   'normalize-space(concat(primary/@sortas,
primary[not(@sortas) or @sortas = ""]))'>

with:

<!ENTITY primary   'normalize-space(concat(primary/@sortas, " ",
primary))'>

Now if an indexterm has @sortas, then it is sorted and grouped by a
combination of 
@sortas, space, and the entry, the latter to keep indexterms with
duplicate @sortas values separate. If an indexterm does not have @sortas,
then the first item in the concat is empty, and the space is removed when
normalize-space is applied, leaving just the entry.
