Viva.
Se eu percebesse alguma coisa de namespaces talvez te pudesse ajudar,
mas em 2 creio que deveria ser
<xsl:value-of
select='fn:count(//def:record[def:metadata//dc:subject="current()/."])'/>
ou se nco resultar tenta declarar uma variavel antes e usa-a na comparagco.
Se nco der, tb ja nco sei mais...
(Sorry for the post in Portuguese, it's easier for me...)
