Yeah... Found things like:
THISisNOTaVALIDVersion: 1  (appears to be valid in the test cases that I've written.
// Version: 1.0. (appears to be valid as well despite the trailing .)

I was wondering about things like:
- Do we require a space after //
- Do we support a version like: // Version: 1.x (this is actually valid with the current code)
