RE:  Pattern question: first child of first descendant
I think it's

match="entry[. is
ancestor::table[1]/descendant::entry[1]]/*[self::title|self::para][1]"

Note the use of "is" rather than "=".

When matching complex patterns like this, it's sometimes best to preselect
all the matching elements into a global variable:

<xsl:variable name="initial-paras"
select="//table/descendant::entry[1]/*[self::title|self::para][1]"/>

<xsl:template match="*[. intersect $initial-paras]">
