I guess so, I propose three mechanisms:

1. Given an attribute name / value, provide validation (yes / no /
unknown)

2. Given a partial value string for a named attribute, provide a list of
auto-complete alternatives

3. Given a named attribute, provide means to launch a helper program /
function to fill in the value

What this doesn't quite address (as I understand your comment), is the
possibility that the validation / selection process is based up other
attributes attached already / in the schematic etc..

Any insight about how you see this being used would be greatly
appreciated. Seems to me it goes some way to providing "integration" in
a much needed area, without tying programs too explicitly to each other.

Regards,

Peter C.
