Well, the minimum change is:

> <xsl:variable name="label-nodes">
>      <xsl:choose>
>          <xsl:when test="local-name() = 'shared'">
>              <xsl:sequence select="rm:label[$page-type = tokenize(@pages,
'\s*,\s*')]"/>
>          </xsl:when>
>          <xsl:otherwise>
>              <xsl:sequence select="rm:label"/>
>          </xsl:otherwise>
>      </xsl:choose>
> </xsl:variable>

But I think I would write

<xsl:variable name="label-nodes"
  select="rm:label[local-name(current()) ne 'shared' or $page-type =
tokenize(@pages, '\s*,\s*')]"/>
