Again identity template is your friend. Keep everything as before
with identity template passing through the default. Then add a more
specifically matching template like:
<xsl:template match="conceptName[tags/conceptNameTag/tag='preferred']">
<conceptName>
<tags/>
<conceptNameType>FULLY_SPECIFIED</conceptNameType>
</conceptName>
</xsl:template>
This *should* (not tested) match any conceptName with tag='preferred'.
And write out a new conceptName as above. What do you want to do
with any other tags you might have? The above simply ignores them.
Cheers
