"extends" is not available with rules generated from decision tables. Whileit wouldn't be a big problem to add an option for adding "extends x" to the
rules generated from one table (or even a different extends clause to each
of the rules resulting from a table) I can see a problem for coming to grips
with what the user will need to write for "x".
If "x" is the name of a rule that's defined in a separate DRL: no problem.
But what if the user want to extend a rule from another decision table?
They have names concocted from a user supplied name and the row in
the spreadsheet. The only way to have a reliable reference would be via
spreadsheet native cell references.
