multiple paths in the "use" in key....I'm getting des

Im getting desperate: I've been fighting this problem for 10 hours now....

And I'm sure the solution is quite simple.

I want to take the address codes in AddressSpecific: (municipalitycode,
streetcode,
streetbuildingIdentifier)
and look them up in the XIaddressSpecific element AND RETURN THE CORRECT
XIaddressSpecificLabelStructure

How do I do that?

I have been trying using keys, with multiple paths in the "use":

      <xsl:key name="ForwardingAddressPostCodeIdentifier"
match="PostCodeIdentifier" use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier" />
      <xsl:key name="ForwardingAddressDistrictName" match="DistrictName"
use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/dkcc2:StreetBuildingIdentifier" />
      <xsl:key name="ForwardingAddressFloorIdentifier" match="FloorIdentifier"
use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier"/>
      <xsl:key name="ForwardingAddressSuiteIdentifier" match="SuiteIdentifier"
use="
../../AddressSpecific/cpr:MunicipalityCode and
../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier"/>


but the "and" between the paths in the "use" doesn't seem to work. PLEASE HELP
ME! I'm going soon
nuts

on beforehand thanx

          <ForwardingAddressStructure>
             <AddressSpecific>

                        <StreetBuildingIdentifier>135</StreetBuildingIdentifi
