Larissa,

Have you check to see it there is an open bug for this?

The RFC would seem to indicate that the problem is known. And that it 
was considered in RFC45, but it is not clear from the RFC that it was 
actually solved as there is no bug number at the bottom that 
specifically tracks that particular change. This RFC was targeted for 
Mapserver 5.4.

If you are on 5.4 or later then you might want to get a ticket opened 
asap, and maybe a fix can get put in 6.0 to resolve this.

Steve L, Thomas B, - Do you guys know if this was tackled or not?
