Processing instruction at root of test data: test always fails

[GoogleCodeExporter]

If the expected test data contain a processing instruction next to the root 
element, e.g.

<?xml version="1.0"?>
<?xml-stylsheet ...?>
<root>
...
</root>

the test will never succeed, because the PI is somehow lost.

Using xspec-0.4.0rc1.

The same holds for expected results that contain a DOCTYPE declaration (I'm not 
sure this is even possible at all): the document is not well-formed because the 
declaration is in the middle of the text, but the style sheet has to generate 
it.  Can the use of an external file solve this?  Or are there ways around this 
problem?

Thanks!
