I think I was trying to ask, is the template content of a variable
treated as its own document? It would make sense if it were, considering
it's possible to create new nodes within it, rather than creating a set
of references to nodes in the original document when @select is used.
Then exsl:node-set() essentially acts like document(), correct? I think
I was getting confused because I started out making copies of the nodes
in the template content.

Technically there's no such thing as the "context document", though it's
a
convenient shorthand for "the document containing the context node".

Correct, when you apply-templates to a node that node becomes the
context
node.

If you need to refer back to the original document, it's usually best to
have a global variable bound to it.

<xsl:variable name="main-doc" select="/"/>
