  '14.3 tell us that:

    If the group-by attribute is present, then an item in
    the population may have multiple grouping keys: that is,
    the group-by expression evaluates to a sequence. The
    item is included in as many groups as there are distinct
    grouping keys (which may be zero).

  On the elements that don;t have this attribute, the
group-by expression will evaluate to a zero-length sequence,
so they will be included in zero groups.  If you want to
have a group for empty values (for example by handling "no
attribute" as the same as "attribute with empty value"), you
can use the following:

    <xsl:for-each-group select="current-group()"
