DocBook

Specifying paths with a leading dot causes problems, for example:

<xsl:param name="html.stylesheet" select="'./docbook-xsl.css'"/>

This generates validation errors like:

ERROR: article.epub/OEBPS/index.html(4):
'OEBPS/./docbook-xsl.css': referenced resource missing in the package

The file is in the archive at the correct location, just doesn't
seem to like './' in the path name -- the path needs to be normalized
before being written to the contents.opf.

It's not just the valdiator, the file is missing when the EPUB is viewed
(in bookworm).

This works fine:

<xsl:param name="html.stylesheet" select="'docbook-xsl.css'"/>

Environment: DocBook XSL 1.75.2; Ubuntu 8.04
