RE: [xsl] Indenting Blocks in HTML Output

["Michael Kay" <michael dot h dot kay at ntlworld dot com>]

There are two ways to do this. One is to pass the current depth (or the
indentation string) as a parameter when you do the apply-templates. The
other is, when processing each node, use count(ancestor::*) to determine
its depth in the original tree.
