While an SDD instance document may contain more than one set of descriptions for different purposes, The group of taxa described within each description is not set and may contain any subset of <a href="taxonnames.html"><TaxonNames></a> or <a href="specimennames.html"><Specimens></a>. The scope element is applicable within any element nested within <SDD-DescriptiveData> (<a href="naturallanguagedescriptions.html">natural language descriptions</a>, <a href="codeddescription.html">coded descriptions</a>, and <a href="dichotomouskeys.html">dichotomous keys</a>) and allows a definition of the entities covered by each distinct description. For example The <Scope> element could be used to define a set of descriptions as refering to mandibles of immature male Lycanthropes of Wisconsin.

A simple SDD instance document for defining scope has the basic structure shown below.

The scope of a dataset may be defined with reference to taxa or specimens. Multiple taxon names may be used to express ambiguities or groupings for which no higher taxon name exists (e. g., species from a geographical region). Taxon names may include a <citation> to the original source of the scope definition. Specimen scopes refer to the original physical object and may include reference to a geographical locality.
