Is it a requirement that ALL things in the language be scoped?

Is it required they be declared in the grammar given that if 
there is a grammar, there is already a way to declare an ID? 

xml:id and xml:idatt only work if the standard means of 
declaration has been avoided.

There isn't a gap in the architecture.  There is a flawed 
practice for which the requirement posted thus far is XPointer 
raw and streaming.  These should be the contexts for choosing 
the solution IF any.

1) They're not scoped, everything else about the language is.
2) They're not declared in the grammar (DTD/Schema), so their usage is not
subject to any declarative/universal quality control: you're back to
writing ad-hoc code in every application to check they occur where and 
how they're supposed to.
