I've added some markup to populate the array.

You can populate an AuxSelect array via markup:

  (:auxselectdata arrayname [value1 [value2 ...]] :) 

e.g.

  (:auxselectdata somearray fred barney 'dino dog':) 

and immediately use it:

  (:auxselect test somearray text='Somearray: ':) 

auxselectdata has limited use on a single page ? although the selection 
will persist should recipe authors wish to use the value elsewhere ? but 
it can be used in group and site headers with more effect[1].

For security reasons, you cannot overwrite an array that has already 
been defined.


[1] Unfortunately, it appears that markup in group header (and site 
header when defined) runs after PageText markup, so my suggestion above 
about using this, in effect, as a replacement for using config.php (and 
friends) doesn't hold.
