I thought we were wanting to create OAI DC, instead of the srw_dc?...  Shouldn't we just get rid of the whole `choose` bit? Really, couldn't this template be rewritten:
```xml
<xsl:template match="/">
  <oai_dc:dc xsi:schemaLocation="http://www.openarchives.org/OAI/2.0/oai_dc/ http://www.openarchives.org/OAI/2.0/oai_dc.xsd">
    <xsl:apply-templates select="//mods:mods[1]"/>
  </oai_dc:dc>
</xsl:template>
```
