xsl:key, xsl:apply-keys -- proposal and implementation

Dear xsl editors,

I made on xsl-list a proposal clarifying the semantics of xsl:key and
suggesting the addition of a new xsl:apply-keys declaration to allow
more than one root from which indexing (i.e. the creation of key
entries) may proceed.  This is mainly useful in conjunction with the
document() function.

I offer a prototype implementation in XT at the following URL:

               http://www.ps.uni-sb.de/~duchier/XT.tgz

This contains a description of my proposal in the README file which is
also available individually at URL:

Sincerely,
