Yeah. This neatly sums up the problems I've been having. An XPath expression
always seems to return an entire sub-tree, and it seems to me that I just want
a single node in this case. Will xsl-copy give me that?

Not true. xsl:value-of takes the first element from the node-set that results
from the expression
"foo" and converts that to a string. As both sub elements <bar> and <p> are
_inside_ element <foo>,
their textual content is returned as well.
The output is therefore: "
this is the value of foo
this is the value of bar.this is the value of a paragraph that is the
child of bar
"
(including new-lines when white-space is preserved)
