I don't see the usefulness of such key (if you can concatenate the
string value of the two elements, you certainly have them already.

But here is one way of constructing such key anyway:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:key name="kX"
           match="datafield[@tag='773']/subfield[@code='5' or @code='t']"
           use="concat(../subfield[@code='5'], ../subfield[@code='t'])"/>

 <xsl:template match="datafield[@tag='773']">
   <xsl:copy-of select="key('kX', concat(subfield[@code='5'],
subfield[@code='t']))"/>
 </xsl:template>
</xsl:stylesheet>

When this transformation is applied on the provided source XML document:

<collection>
 <record>
  <datafield tag="773" ind1="0" ind2=" ">
   <subfield code="5">BULLETIN / EIDGENOESSISCHE TECHNISCHE HOCHSCHULE
ZUERICH </subfield>
   <subfield code="t">Bulletin / EidgenC6ssische Technische Hochschule
ZC<rich </subfield>
   <subfield code="d">ZC<rich : Schulleitung der ETH ZC<rich, 1993-2005
</subfield>
   <subfield code="g">S. 27-33</subfield>
  </datafield>
 </record>
</collection>

the wanted, correct result is produced:

<subfield code="5">BULLETIN / EIDGENOESSISCHE TECHNISCHE HOCHSCHULE
ZUERICH </subfield>
<subfield code="t">Bulletin / EidgenC6ssische Technische Hochschule
ZC<rich </subfield>

Cheers,
Dimitre
