Key length and location

This document describes the location and the length of text keys.

The length of descriptor and numeric keys is implicit in the type. For text keys, it must be explicitly defined; the length of text keys is set at construction time.

The location of a key within an array element is defined by the offset of the key from the beginning of the element. The _FOFF macro can be used to define the offset value.
