Purpose
A 
allows a serialised query to represent the membership of a subset of 
. A query contained in the 
is run against the content of 
to produce a subset of 
, 
or 
. The query is referred to an intensional definition of the subset. It can be run against future releases of to generate an updated set of subset members.
The members of the resulting subset may also be represented in an enumerated form as a 
. An enumerated representation of a subset is referred to as an extensional definition.
Data structure
A 
is a 
containing 
that represent intensional definitions of subsets of 
. The result of running the query is an extensional representation of the subset of which can be represented as a . Its structure is shown in the following table.

Example Data
In the example below, "serialised query 1" is a text string that can be used to generate members for 
1, which is a simple member (without any additional fields within its member records).
