As far as I know, you can't use a temporary tree to compose
stylesheets at all. You have to write the output of one stylesheet,
and read it again in the second.

Hello,
I am currently thinking about the limitations of stylesheet
compositions. As far as I know stylesheets can run after another where
the subsequent one might work on the complete result of the precesding
one (using temporary trees). I think it is impossible to let the second
stylesheet run only on the data the first one added to the source xml
without changing the stylesheets. Let me pose an example:
XML:
<aaa>1</aaa>
<aaa>2>/aaa>
Stylesheet1 just adds some more <aaa> to the source, so that the xml
after the transformation looks like:
<aaa>1</aaa>
<aaa>2</aaa>
<aaa>3</aaa>
<aaa>4</aaa>
Stylesheet2 matches the "aaa" elements and applies some transformation,
e.g. an addition, plus one, so that the output would be:
<aaa>2</aaa>
<aaa>3</aaa>
<aaa>4</aaa>
<aaa>5</aaa>
My question is the following: Is it possible, without changing
stylesheet1 or stylesheet2, to let stylesheet2 run only on the elements
stylesheet1 has added, so that the output would look like:
<aaa>1</aaa>
<aaa>2</aaa>
<aaa>4</aaa>
<aaa>5</aaa>
?
If this is not possible, would this be something the XML community is
interested in?
I think it would be nice to have some kind of operator that would tell
the second stylesheet if it should work on the complete result of the
first one or only on the added elements.
Has someone already done any research about the limitations of
stylesheet composition and proposed an improvement? Or is the XML
community just fine with current facilities of stylesheet composition?
