I think this is a case where your code is sufficiently wrong that I
can't work out what it's trying to do, which means I can't tell you how
to correct it. I think you need to explain the problem you are trying to
solve - the most effective way of doing that is usually with specimen
input and output.

Of the two nearly parallel statements below, (2) raises the error:
"Sequence of more than one item not allowed as the second operand of
'eq'."
(1) groups-by the attribute ($format) and (2) by all the not ($format)
attributes found in <Formats>. My thinking was that in (2) the
'group-by' would return a current-group() resolved to a single
attribute by the <xsl:for-each select"current()> statement, but if so,
I am clearly addressing that single attribute incorrectly. On the
other hand, no error is reported when in (2) the
group-by="@*[not(name(.)=$format)] resolves to a single attribute. Can
I specify the <xsl:if test="$item eq ???"/> to avoid this error in (2)
and still test against all of the not($format) attributes?
Thanks,
