Namespace URI schemes

I've realised I don't understand one of the points being made 
here.  Several times someone has said something like "if http:// URIs don't 
provide the uniqueness and stability requirements you need, then use 
something else, such as mid://".

Who is the "you" in this statement?  Is it the author of layered 
specifications, or is it the author of XML documents?  Is it open to, say, 
the "XML Schema"  authors to require an http:// namespace URI, or must they 
leave this choice to the creators of particular namespaces/schemas?

[[I know that XML Schema does not actually say anything like this at present]]

I know that in a sense this is a silly question -- of course a layered 
specification _can_ say what it likes.   I'm asking how this is all 
intended to work in the vision of those making the statement.
