The processor shouldn't do that: if you call document() twice with the same
URI, it's obliged to return the same root node each time (so
count(document('A.xml')|document('A.xml')) is guaranteed to be 1).

But it's not a bad idea to put the call on document in a global variable
anyway:

<xsl:variable name="B.xml" select="document('B.xml')"/>

and then you can replace your calls on document('B.xml') with a reference to
$B.xml
