Added case() function and moved text about extra dependencies introduced by index()

All,

I added the case function to the 'XPath expression module' [1]

I also replaced the paragraph about the additional dependencies for the index() function [2] by:

"A function can introduces additional dependencies, the additional dependencies should be defined in the module that makes the function available to the XForms engine. It is recommended to define the additional dependencies as if it were dependencies to implicitly managed instance data nodes."

I made this change, because the actual text is now in the 'XPath expression module' [3], I also added the text for the case() function. (The main spec shouldn't reference things that are defined in theXPath Expression module)

Could you all have a look at these changes and give your remarks?

Kind regards,
