Please direct all questions to the dev list. The only reason is that it
seems hard to implement it efficiently. Consider:
foo
jx:attribute name=bar namespace=http://www.bar.org; value=${bar}/
jx:if test={$fubaz 1}
jx:attribute name=xyz value=100/
/jx:if
jx:forEach var=item items=${items}/
jx:attribute name=${item.name} value=${item.value}/
/jx:forEach
...
/foo
The start element event for foo must be buffered until all potential
jx:attribute tags have been processed. Since these are within
conditional blocks and loops determining when that is the case in an
efficient way isn't easy.
It looks like you have to buffer foo until you reach another startElement or
get a endElement for /foo.Am I missing sth?

After a longer thinking it really does not look so easy. As it is not known if
an element has dynamic attributes or not the start element on the output would
have to be postponed for EVERY elemeny till we reach startElement for a child
node a endElement for current one.
Still I do not see any efficiency issuses here: only one element has to be
cached so it does not impart neither speed nor memory requirements.

... or a characters() event containing non-whitespace.
Whitespace characters() between an element an jx:attribute should not be output at all.
