Whew. I was afraid that by posting that at 5:30 in the morning,
I'd be making apologies for it today :)

Yes, just left over from a previous version of the code... should have been
[@name=name()] but it's probably not necessary, given the way I structured the
xsl:if tests. I was thinking it would help prevent a match when there is more
than one ignorable element specified with the same attribute names.

When you bind a variable by specifying the value in the content of the
xsl:variable element, rather than via an XPath expression in the select
attribute, the value is always a result tree fragment consisting of a root
node, plus children that are whatever other nodes you generated. In this case
we end up generating 1 or more text nodes containing "1" (and they get
normalized into a single node with text "1" or "11" or "111"...). The fact
that I chose "1" as the string was immaterial; it just needed to be something
that would result in the RTF having a non-empty string-value. The reason for
the string() is because an RTF alone always tests as true, because it always
has a root node.
