> From reading the source code (Table.doHeavyIndexing() in the generator), the heavy-indexing
attribute of the table should create an index for every column for a composite primary key.
It has the following flaws in 3.3:
> - It is not documented what the attribute does.
> - It currently does not work correctly. The first column of the composite primary key
is left out (and the comment in the code why this is done is incorrect, because the database
will automatically create a composite index for the combined columns, not an index for the
first column).
> - It would be much more transparent to list the indexed columns as <index-column>.
> Therefore I propose to remove this attribute from the 4.0 schema without replacement.
This would not remove any functionality.
