- When an Ordered Aggregation has a slot, its index must be unique within that Ordered Aggregation. - However, Slots are permitted to be proxies in other kinds of Aggregation, in which case index uniqueness is not required. -
-- When a Slot has an ordered list, its index should be less than or equal to the length of that Ordered List. + The index of a Slot should be less than or equal to the length of its ordered list.
+ No thing. +
++ Any thing. +
+- An Aggregation which may have slots that are orderable by numeric index. + An Aggregation which may have slots that are orderable by positive integral local notation.
+ A Proxy which has a local notation, unique within the Aggregation that it is proxy in. +
+- An integer, string, or time·stamp which identifies and orders a thing within a given context. + An integer, string, or time·stamp which identifies and orders a thing within its local context.
String values can either be valid
- A Slot in this Ordered Aggregation.
+ A Slot in this Aggregation.
+ The local context for this thing, in terms of which its properties should be considered.
+
+ If a thing does not have an inherent local context, local contexts (and associated properties) may be added thru the use of Proxies.
