Re: Interpretaion of grouping for-each

> Does it go through viewentries which have dont have repeat key values?

No it selects the first (in document order) viewentry with each key
value (even if that key value is not repeated).

See any description of muenchian grouping, eg Jeni's site.

<xsl:for-each select="viewentry
that selects all viewentries then
key('ve-by-firstocc', substring(entrydata[3]/text,1,1))
selects al the entries with the same key,
so
key('ve-by-firstocc', substring(entrydata[3]/text,1,1))[1]
selects the first of that group
and
count(. | .....) =1 
id the currently selected viewdata is that first element.
so
viewentry[....]
just selects the first entry in each group as teh predicate is false in
other case.
