[Therion] Is survey -namespace off and sometimes on possible in same survey project?

[Stacho Mudrak]

Hi Bruce,

as far as I know, namespace could be specified for individual surveys. I am
just afraid, this feature has not been tested a lot, so please let me know
if some unexpected behavior occurs.

Thanks, S.
