[Simple-support] BUGs collection

[Simon B. <sim...@if...>]

Dear Niall,

As you might work on a new release soon, I wrote some further test classes
illustrating other bugs/problems that I frequently observe when using the
framework.
(By the way, I like the simple-xml framework very much)
The files include FIXME comments that point to the problem.

Best Regards and thanks for your work

Simon
