It could do this now already. It's just a matter of specifying an alias.
A rule like
TMyEnum. -> TMyOtherEnum.
would do it. (the dot meaning that all identifiers starting with TmYEnum
must be remapped)

But personally, I don't want the linear XML structure disturbed.
I edit the xml files manually, and having a 'tree like' XML then makes 
it more difficult to edit.

But the fpdoc editor is another matter. You could perfectly adapt lazde 
to show a tree:

   +- One
   +- Two
Same for classes functions, procedures, whatnot. It's just a matter of
scanning the element name and creating separate nodes for each part in 
the dotted name.

I can appreciate that this would be a useful option (and maybe even the
default view).
