Here is a solution using the node-set extension function:
Sorry, I didn't state it explicitly, I need xslt 1.0 for browsers (no
extensions),
but thanks anyway.

One simple way to do this:
The following transformation:
<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="kb" match="b[not(. = ../../e2/f/@c)]" use="."/>
<xsl:key name="kb" match="@b1" use="../../../e1/b[. = current()/../@c]"/>
<xsl:key name="kDist" match="b | @b1" use="."/>
<xsl:template match="/">
<e3>
<xsl:for-each select="key('kb', */e1/b)[generate-id() =
generate-id(key('kDist', .)[1])]">
<xsl:sort/>
<b2><xsl:value-of select="."/></b2>
</xsl:for-each>
</e3>
</xsl:template>
</xsl:stylesheet>
when applied on the provided source xml document:
<a>
<e1>
<b>abc</b>
<b>abd</b>
<b>abe</b>
<b>abf</b>
<b>abg</b>
<b>abh</b>
<b>abd</b>
</e1>
<e2>
<f c="abe" b1="abc"/>
<f c="abf" b1="abj"/>
<f c="abg" b1="abi"/>
<f c="abh" b1="abi"/>
</e2>
</a>
produces the wanted result:
<e3>
<b2>abc</b2>
<b2>abd</b2>
<b2>abi</b2>
<b2>abj</b2>
</e3>
I'm still fascinated by Dimitre's solution. I also tried a first modification
(but without success): <e1> represents a response from a web service,
but <e2> is supplied by me and fairly static. So it would make sense to
put it in a separate document (teste2.xml), to enable the browser to cache it.
<e2>
<f c="abe" b1="abc"/>
<f c="abf" b1="abj"/>
<f c="abg" b1="abi"/>
<f c="abh" b1="abi"/>
</e2>
The first key definition
<xsl:key name="kb" match="b[not(. = ../../e2/f/@c)]" use="."/>
I assume should become
<xsl:key name="kb" match="b[not(.
=document('teste2.xml')/e2/f/@c)]" use="."/>
but I have no idea how to change the second
<xsl:key name="kb" match="@b1" use="../../../e1/b[. = current()/../@c]"/>
How can I get a xpath expression for the (primary) source document if the
context is in another source document?
