External Import

This confused me to no end at first, and I came across it in the code again, so... here's the suggestion:

TERMS:
disabledOperations:
--> context: ['tx_my_table']['ctrl']['external']['index']
--> Basically it means that all the fields in this index for this table should not update / insert / delete depending on how this is set.

excludedOperations:
--> context: ['column']['external']
--> This is a per column exclude that denies update / insert depending on the setting.

SUGGESTION:
The terms 'excluded' and 'disabled' can be semantically identical, especially in a coding context. So, I would suggest both the identifiers be renamed thus:

tableDisabledOperations
columnDisabledOperations

...so as to distinguish context specifically. Either that, or call them both the same thing, but make the point that there are two contexts for the identifier.

OFFER:
If this is desirable, I can make the changes and submit a patch(s).
