[Product-Developers] passing variable definitions and accessing schema fields

How would one get the value of a subscriber variable in the  
DisplayList vocabulary of a custom type schema?  For instance, I have  
the following code in a subscriber to get a member's email address,  
but I need to pull it from there and/or pass the value to a custom  
InAndOutWidget field for creating an email list:
     # get member's email address:
     from Products.CMFCore.utils import getToolByName

How would I pass the value of $mymail to my vocabulary=DisplayList?   
Or incorporate this instead into the schema definition?

I would also like to re-use the date (startDate and endDate?) fields  
and mail text field (text?) of the Event schema in a custom type, but  
I can't figure out how to use accessor methods to access their  
content.  I'm not even sure that startDate, endDate, and text are the  
proper field names: though they appear to be so in the ATEvent schema  
code, trying to access these names (with 'accessor=') results in  
attribute errors.
