4 was a mistake (follows 3 I guess).
I would have caught the boolean mistake... thanks for catching that
for the sake of the post!

Ok, 2 responses now say to create a variable of the root source. I
was going to ask if this was possibly inefficient or if this is not a
preferred workaround but sounds like it is fairly standard practice.
Would that be a correct assumption?

The following xml document is our main document, which I still don't

<foo>1</foo>

<foo>99</foo>

Lets say our XSLT creates a global variable "foo_test" and it imports
an external data source which looks like:
<foo_test>
<foo>3</foo>
<foo>99</foo>
</test_foo>
Will the following expression work:
<xsl:apply-templates select="data/foo = $foo_test//foo"/>
The expression (data/foo = $foo_test//foo) returns the boolean value true,
indicating that a match exists. xsl:apply-templates can only be applied to
nodes, not to booleans.
If you want to apply templates to all nodes in <data> that have a
counterpart in <foo_test>, you can use:
<xsl:apply-templates select="data/foo[. = $foo_test/foo_test/foo]"/>
Resulting in a match on:
foo = 3; and foo = 4
Where did you get foo = 4 from?
Now, let do the reverse of this and match on all $foot_test foo
elements so we have:
<xsl:apply-templates select="$foo_test//foo" mode="my_external_foo"/>
And we have the template:
<xsl:template match="foo" mode="my_external_foo">

Assign a global variable to the "main XML source" using
<xsl:variable name="root" select="/"/>
