[Mono-devel-list] patch for mcs /doc (phase 1)

[Atsushi Eno]

Hello,

Currently mcs does not support XML documentation generation. So I
made an easy hack around it.

There are some TODOs:

	- Currently this patch does not consider parser's look ahead,
	  so in some places it incorrectly consumes XML documentation
	  put on other members. Thus, it consumes documentation after
	  enum type.

	- For the same reason above, documentation on delegate are
	  never be consumed.

	- I could not acquire the full type name of operator's
	  parameter(s) in cs-parser.jay. It would be possible
	  if I dug into operator resolution, but currently not yet.
	  (am not familiar with the compiler code ;-)

	- Check for incorrect location for documentation are
	  insufficient. For example, documentation inside method
	  body will result in an inconsistent document.

	- mcs never provides precise XML error location (if exists).

	- There might be some XmlWriter bug around indentation (well,
	  it's just my TODO ;-)

Comments are appliciated.

Gert: Do you think we can use it for ndoc? (Though unstable, I know ;)

Thanks,
Atsushi Eno
