I'm only guessing here, but could it be that the namespace prefix core: maps to
different namespaces uris at these two points?  That's somewhat variable, isn't
it?

For example:

<xsl:template match="main" xmlns:core="something">
    <xsl:value-of select="//core:type[@id='publisher_type']/@id"/>
</xsl:template>

vs...

<xsl:template match="later" xmlns:core="something-else">
    <xsl:value-of select="//core:type[@id='publisher_type']/@id"/>
</xsl:template>

or worse...

<xsl:template match="worse">
    <xsl:value-of select="//core:type[@id='publisher_type']/@id"/>
</xsl:template>

I know it's a stretch, but these three templates return different results for
the same document.
