This document uses the following terms:

fragment: The term "fragment" that is defined in [XDM/2].

schema collection: A collection of XML schema [XMLSCHEMA1/2] components, such as attribute, element, and type declarations, that belong to one or several target namespaces. A schema collection can be used to constrain an XML data type in SQL Server and provides type information for the nodes and values in an XML data type instance.

XML: The Extensible Markup Language, as described in [XML1.0].

XML schema: A description of a type of XML document that is typically expressed in terms of constraints on the structure and content of documents of that type, in addition to the basic syntax constraints that are imposed by XML itself. An XML schema provides a view of a document type at a relatively high level of abstraction.

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
