Q: How Do You Know That XPath 2.0
Thinks It Is a Programming Language?

Because it has comments!

• Comments
  • may occur inside expressions
    (anywhere ignorable whitespace is allowed)
  • are strings
  • may nest (so you can comment out expressions containing comments!)
• Comment delimiters are (really, this is not a joke)
