<xsl:sort select="
monogr/author |
self::*[not(monogr/author)]/analytic/author |
self::*[not(monogr/author | analytic/author)]/monogr/editor |
self::*[not(monogr/author | analytic/author |
monogr/editor)]/monogr/title"/>
I think for XSLT 1.0 you can simplify that select to:
<xsl:sort select="(monogr/author|analytic/author)[1]"/>
I don't think so. That will select the first in document order, not the
first in the order of precedence defined in the requirement statement.
