comments

<!-- here is some comment --
                            ^
                            |
                    what can be here apart from '>'?

XML seems not to like '--' inside comments. I read somewhere that '--' switchs some modes inside <! ... > thing, but  (even number of --s) seem to be invalid too. If it is some historic feature, what is "pro" part of it? ("contra" part is inability to have -- in comments).

What is the reason of complicating comment processing by not making just '-->' end of comment and allowing '--' inside?
