node tests with keys
If you're using predicates, remember that the context node changes inside
the predicate. Use current() to get around this:

for-each B
  value-of select="//A[@attribute-of-A = current()/@attribute-of-B]

However, using keys is easier and more efficient:

<xsl-key name="k" match="A" use="@attribute-of-A"/>

<xsl:for-each select="B">
   <xsl:value-of select="key('k', @attribute-of-B)"
