troubles with test cases

[Oleg G. Sharov]

Hi!

I have troubles sorting issues attributes in 'dt ls --xml' test cases.
Issue attributes order differs when I get data from "shelve" and when I get 
data from disk. 

I see 2 ways of solving this problem:
1. sort issues attributes before xml output
2. deep modification of diff methods of "dttest" 

I don't like the first method. The second method requires a lot of effort.

Opinions?
