Seems reasonable, I could almost use something like this.  However, it would
seem to me that what you want is a dependency graph, and as such,
hierarchical XML might be a good fit, at least as an intermediate format?
IE;

	<stylesheet name="gunk.xsl">
		<import name="blah.xsl>
			<template match="fee" name="foo">
				<parameter name="test" default="0"/>
			</template>
		</import>
		<template match="root">
			<call name="foo"/>
		</template>
	</stylesheet>

would alert you to the fact that the "root" template can end up invoking the
"foo" template without passing it the "test" parameter (but there is a
default defined for this case).  Of course, this is only better than the
original source in that it eliminates some of the noise and makes the import
targets more obvious.  However, it should be relatively easy to produce?

The problem I see with a VB type pseudo code is that I don't see how you
would map multiple match targets without getting into building (possibly
large) switch statements all over the place; the output could be bigger than
the input.

After you get the reduced XML output then you could play with rendering it
in SVG :-)
