It would be cool to see the same effort/analysis [insert the right
word there] for how schema awareness does a lot of what the tests will
do, but with the added benefits that go with schema awareness.

For example, you could have input like:

<title>a title</title>
<body>the body</body>

...and you write a unit test to ensure the output contains a <title> -
or you could have a result schema with a mandatory <title> element,
the template which outputs the title could have an "as" attribute and
if you had an input schema you could be sure your XPaths were actually
selecting that title in the input.  All of which seems preferable to
the unit test.

A lot of time, effort and money goes into testing, but for XSLT, I
think that effort would be better spent on fully schema aware
transforms than unit testing.  What do you think?
