Generally reference to a single SamplingStage or to a Sequence which orders multiple SamplingStages. TypeOfObject should be any valid member of the group of Control Constructs.

The survey population is the set of elements identified by the frame. For instance, pre-election polls have "likely voters" as a target population, but the survey is conducted using RDD (usually). The survey population is households with active land-line telephones, because that's who we can initially identify. Survey questions help narrow the respondents into the desired set, but then eliminating sampled units increases variance. It is reusable in the sense that the same survey population will be used each time the named frame is used.

A description of the population that the survey is intended to question (i.e. "Likely voters").

Full description of the sampling plan. Supports multiple language versions of the same content as well as optional formatting of the content.

A full display label for the sampling plan, repeatable for different context or applications. Supports multiple language versions of the same content as well as optional formatting of the content. Repeat for labels with different content, for example, labels with differing length limitations.

A name for a sampling plan which may be repeated to express differing names for different systems. May be expressed in multiple languages. Repeat the element to express names with different content, for example different names for different systems.

Rationale for dividing the frame at this stage into subsets and using a different sampling technique (e.g., Simple Random Sampling or Probability Proportional to Size) on each subset.

Describe the purpose for stratifying the sampling process.

A controlled vocabulary covering probability and non-probability sampling methods and modeling approaches. If this is a multi-stage sample the plan at this level should indicate the broadest description of the sampling approaches used in each stage.
