AttributeDefinition - Multiple sourceAttributeID

> Is it possible to have multiple sourceAttributeID in the AttributeDefinition?

If I understand you correctly you need to add the attributes or data connectors as dependencies.  The attributes will be available to your script:

> A variable for each attribute produced by the defined dependencies of this definition. The variable's 
> name will be that of the ID of the attribute from the dependency. In the event that more than one 
> dependency produces attributes with the same ID the values of all of those attributes will be merged and 
> made available to the script.
