[support] Scope of user-defined content type field identifiers

[Andy Heath]

Drupal 7.4

Seems a bit wierd to me - field identifiers/labels on out-of-the-box 
content types behave as local to the content type - i.e. one can have 
the same identifier on fields in different content types (such as Title 
and Body example). And when I create a new content type I get these 
local names for free.  Yet when I try to re-use names in different 
content types Mr. "don't do naughty things" says "you can't do that 
because the name is already in use" - i.e. user-defined field names 
behave as if they are global.

Is there some reason for this and any way around it ? Its quite limiting 
having to artificially choose different names for the same thing in 
different records (for example if I'm using a Tag field with its own 
vocabulary in more than one record - if I want to define a content type 
that has a Tag field I can't unless I call it something else because the 
name is in use).

I'm a bit of a drupal newbie but learning fast.
