Problem raised by Vladimir Nestorovsky today on the xsl-list at mulberrytech.

The specification of xsl:for-each-group is unclear as to the order of items in
each group (that is, the result of current-group()).

The intent is that the procedural algorithm given for each of the four grouping
methods defines this order. But this relies on understanding that when an item
is "added" to a group, or "assigned" to a group, it is added at the end of the
sequence, which isn't explicitly stated.

Suggestion: in the rules for the four grouping methods, change "added" and
"assigned" to "appended", and add a sentence at the end saying that the order
in which items are added to each group determines the order of the items in the
group as returned by the current-group() function.
