+/* The memory store is currently highly experimental. It's meant to become
+ a base store used by other stores for internal caching (for full caching
+ support, aging needs to be added).
+
+ The database use is meant to support as much attribute association as
+ possible, while providing for as small search ranges as possible.
+ This is currently provided for by sorting the entries by numbers that
+ are composed of bits set at the positions indicated by attribute type
+ codes. This provides for ranges determined by the highest attribute
+ type code value. A better idea might be to sort by values computed
+ from the range of attributes associated with the object (basically,
+ the difference between the highest and lowest attribute type code)
+ and it's distance from a base (basically, the lowest associated
+ attribute type code).
