/**
* Normalize the information for an SMW object (page etc.) and return
* the predefined ID if any. All parameters are call-by-reference and
* will be changed to perform any kind of built-in normalization that
* SMW requires. This mainly applies to predefined properties that
* should always use their property key as a title, have fixed
* sortkeys, etc. Some very special properties also have fixed IDs that
* do not require any DB lookups. In such cases, the method returns
* this ID; otherwise it returns 0.
*
* @note This function could be extended to account for further kinds
* of normalization and predefined ID. However, both getSMWPropertyID
* and makeSMWPropertyID must then also be adjusted to do the same.
