  Hi all,

issue:

I'd like to ask for the review of the issue 188593 - schema enabled xml 
files attributes auto-completion is broken

Description: Several problems with xml schema completion of attributes 
(bad insert offsets, doesn't offer anything)

Impact:
Productivity stopper - It's not possible to use the main features - xml 
schema completion seamlessly.

Risk:
Low. There might potentially be some regressions, but the change is 
straightforward so the chance is minimal.

Thanks,
Marek
