If you put a boolean expression such as ... and ... in the use attribute
then this will have value either true or false, so the all the nodes
will be given one of these two key values and looking up a key with any
other value than true or false will return nothing.

so

after

      <xsl:key name="ForwardingAddressPostCodeIdentifier" match="PostCodeIdentifier" use="
../../AddressSpecific/cpr:MunicipalityCode and ../../AddressSpecific/cpr:StreetCode and
../../AddressSpecific/StreetBuildingIdentifier" />

key('ForwardingAddressPostCodeIdentifier','true') returns all
PostCodeIdentifier elements that have the three cpr: elements at those
relative ocations, and
key('ForwardingAddressPostCodeIdentifier','false') returns all other
PostCodeIdentifier elements.

I suspect this is not what you want but I can't tell from your
description what you do want.

You haven't really stated what you wantto generate and haven't given
eiether a well formed input test file or the desired output but
guessing, you may want something like

<xsl:key name="x" match="XIaddressSpecificLabelStructure" use="
concat(AddressSpecific/MunicipalityCode,':',AddressSpecific/StreetCode,':',AddressSpecific/StreetBuildingIdentifier)
"/>

...

<xsl:template match="ForwardingAddressStructure">
<xsl:copy-of select="key('x',
concat(AddressSpecific/MunicipalityCode,':',AddressSpecific/StreetCode,':',AddressSpecific/StreetBuildingIdentifier)
)"/>

You may need to prefix the element names with a namespace prefix (I can't
say as you didn't show namespace usage)
