11070:
11071: Incoming parameters:

11077: If the institutional status string in undefined, the domain

11079: 3. quota name - portfolio, author, or course
11080: (if no quota name provided, defaults to portfolio).
11081:

11083:

11088: If a value has been stored in the domain's configuration db,

11090: compatibility with domains which have not set up a configuration
11091: db file; the original statically defined portfolio quota was 20 MB).
11092:
11093: If the user's status includes multiple types (e.g., staff and student),
11094: the largest default quota which applies to the user determines the
11095: default quota returned.
