[xsl] Re: empty element sabotages xsl:key

Hi Nick,

I ran your example with MSXML3 -- no problems at all.

With Saxon 5.4 (which uses Xerces)no output was produced.
I know 5.4 is rather old version, but this is what I have.

No, it's OK.

with it until I found an element that, when present, appeared to

<xsl:key>. Is it illegal for an attribute to be set to null?

<OUTSYSNUMBER CODE=""></OUTSYSNUMBER>

I admit to being backleveled.  I think I'm running Xerces 1.0.3
(Xalan.jar
and Xerces.jar that came with LotusXSL 1.0.1).
