RE: [xsl] generating numbers for anchor tabindex

["Michael Kay" <michael.h.kay@xxxxxxxxxxxx>]

Jeni's solution will work, but using generate-id() is likely to be more
efficient. This generates an identifier for a particular node in the XML
source tree, which can often be used as a unique identifier for a node
in the HTML result tree.
