Count() on Distinct, but want to include additional c

I am having a lil issue with a count(distinct element) situation. I am
pretty new to XSLT scripting and the issue seems rather trivial.
Generating the Unique MDBService elements works great but I also want to
include 2 counts per distinct MDBservice based upon MDBDivision.
(ie) count(  MDBService and MDBDivision = "MCAP") & count(  MDBService
and MDBDivision = "HSS")

<xsl:key name="service" match="Activity" use="MDBService"/>
.
.....

<xsl:for-each select="Facility">
	<table width="700" border="1">
	<tbody>
	<xsl:for-each select="Activity[generate-id(.) =
generate-id(key('service',MDBService)[1])]">
		<tr>
		<td>
		<xsl:value-of select="MDBService"/>
		</td>
		<td align="center" width="15%">
		<xsl:value-of select="count("based on MDBDivision =
MCAP")"/>
		</td>
		<td align="center" width="15%">
		<xsl:value-of select="count("based on MDBDivision =
HSS")"/>
		</td>
		</tr>
	</xsl:for-each>
	</tbody>
	</table>
</xsl:for-each>
