However, If you plan on moving your XSL transform to the client sometime
in the future, then the question is like "How do I obfuscate my
super-clever HTML?". And believe me - that way leads to madness

Client-side encryption of code is, by definition, broken.

Why? Because you have to provide: the encrypted code, the decryption
engine, and the decryption key. So all the person at the client side
is read these, and decrypt the code.

Think of it this way: the web browser needs to understand
it eventually ...
