Because the existing dataset that it is proposed to migrate (using a custom 
script):
- is large with many surveys and sub-surveys
- Therion implicitly defaults to -namespace on for every single survey
- with that setting, survey stations, although unique across surveys, cannot be 
seen unless a namespace is specified
- therefore it will not compile until -namespace off is set in each relevant 
survey and sub-survey.

A decade ago, before I was particularly aware of 'survey -namespace', I 
migrated this same dataset, and not being aware I could turn it off, had to 
manually equate stations to join all the surveys, and equate loops where they 
involved more than one survey.  I only did half of it before I got fed up.  I 
realise now that -namespace off is the solution, and that it can be put in the 
custom script.
But in the meantime I have some native Therion sub-projects that I want to 
merge into the migrated project, that, of course, use and rely on the implicit 
default of -namespace on because the stations are not unique (each survey has 
the station sequence 1 2 3 4 ...).  I do not have an appetite to manually make 
these stations unique, even using -station-names to modify them it will be too 
painful.

Hence I am testing the idea of projects where some surveys have -namespace on 
and some -namespace off.
I could modify one of my existing projects to see what happens, but before 
doing that I am interested to find out if others have experience with this 
scenario.

Bruce
