for if-then-else logic you can use xsl:choose with a single xsl:when and
finally a xsl:otherwise.
to test for the existence of an attribute you can use
test="@NAME"
as part of the xsl:when element.

<TIER>
<REGION NAME="CT">89</REGION>
<REGION NAME="MD">135</REGION>
</TIER>
What I want to say is:
If region[@name="VA"] exists
print value of region[@name="VA"]
else
print "0.0"
It is also possible that there will be no REGION elements
<TIER>
</TIER>
I would still want to say:
If region[@name="VA"] exists
print value of region[@name="VA"]
else
print "0.0"
Thanks
