Description

Hello,
I have a problem with a stylesheet containing a xsl:key.

I have the impression that the Transformer object guard into memory preceding xml source.
Here a testcase to reproduce the problem.
The first transformation and the third should produce the same thing.
It is true with Xalan interpretive.
It is not the case in xsltc.
