3.1.4 content model: A framework that identifies the makeup (i.e., data types, multiplicity constraints, ordering) of a specific model.
3.1.5 data type: A property of distinct values that indicates the common features of those values and operations on those values.
3.1.6 extended data element: A data element that is not defined in the LOM v1.0 base schema. See also: LOMv1.0 base schema.
3.1.7 extended vocabulary: A value space that is not defined in the LOM v1.0 base schema for a LOM data element of type Vocabulary. See also: LOMv1.0 base schema.
3.1.8 Extensible Markup Language Information Set (XML Infoset): An abstract data set that provides a consistent set of definitions for use in other specifications that need to refer to the information in a well formed XM L document (W 3C, XM L Information Set). See also: post-schema-validation infoset.
3.1.9 Extensible Markup Language Schema binding (XML Schema binding): A textual representation of the behaviors, attributes, and value space of a data model element in W 3C XM L Schema definition language. 3.1.10 learning object: Any entity, digital or nondigital, that may be used for learning, education, or training. (IEEE 1484.12.1-2002)
3.1.11 learning object metadata data element (LOM data element): A data element for which the name, explanation, size, ordering, value space, and data type are defined in IEEE Std 1484.12.1-2002. See also: LOMv1.0 base schema.
3.1.12 learning object metadata Extensible Markup Language instance (LOM XML instance): A collection of metadata for a learning object that conforms to IEEE Std 1484.12.1-2002, that is represented in XM L, and that adheres to the requirements and constraints of the XM L Schema binding.
3.1.13 LOMv1.0 base schema: A structured collection of standard data items, including their data types, multiplicities, and container/component relationships, as defined in IEEE Std 1484.12.1-2002, Clause 6.
3.1.14 mixed content: An element type has mixed content when elements of that type may contain character data, optionally interspersed with child elements. (W 3C, Extensible M arkup Language [XM L] 1.1)
3.1.15 Multipurpose Internet Mail Extensions type (MIME type): A standard way of classifying content types on the Internet.
3.1.16 post-schema-validation infoset: A transformed version of the XM L infoset of a document produced by a conforming W 3C XM L Schema processor. W 3C XM L Schema defines the data elements added to the XM L infoset of the original document during validation to produce the post-schema-validation infoset. See also: Extensible Markup Language information set.
3.1.17 subelement: A LOM data element that is contained within another LOM data element called an aggregate element. A subelement may contain other subelements; in which case, it is also an aggregate element. See also: aggregate element.
3.1.18 token: A character string. The value space of a token is the set of strings that do not contain the line feed (#xA) or tab (#x9) characters, that have no leading or trailing spaces (#x20), and that have no internal sequences of two or more spaces. The lexical space is the set of strings that does not contain the line feed (#xA) nor tab (#x9) characters, that have no leading or trailing spaces (#x20), and that have no internal sequences of two or more spaces. The base type is normalizedString. Tokens are case sensitive. (Adapted from W 3C, XM L Schema Part 2). See also: token set.
3.1.19 token set: A set of tokens in which each token is unique. See also: token.
3.1.20 uniqueness constraint: A restriction placed on a LOM data element that enforces that the LOM data element is unique within a LOM XM L instance. If a LOM data element has a uniqueness constraint, it  appears in a LOM XM L instance zero or one time.
