Classes related to XMLSchema facets.

The definitions herein are from sections 4.2 and 4.3 of XML Schema Part 2: Datatypes. Facets are attributes of a datatype that constrain its lexical and value spaces.

Facet
The base class for facets.

ConstrainingFacet
One of the facets defined in section 4.3, which provide constraints on the lexical space of a type definition.

_LateDatatype_mixin
Marker class to indicate that the facet instance must be told its datatype when it is constructed.

_Fixed_mixin
Mix-in to a constraining facet that adds support for the 'fixed' property.

_CollectionFacet_mixin
Mix-in to handle facets whose values are collections, not scalars.

CF_length
A facet that specifies the length of the lexical representation of a value.

CF_minLength
A facet that constrains the length of the lexical representation of a value.

CF_maxLength
A facet that constrains the length of the lexical representation of a value.

_PatternElement
This class represents individual patterns that appear within a CF_pattern collection.

CF_pattern
A facet that constrains the lexical representation of a value to match one of a set of patterns.

_EnumerationElement
This class represents individual values that appear within a CF_enumeration collection.

CF_enumeration
Capture a constraint that restricts valid values to a fixed set.

_Enumeration_mixin
Marker class to indicate that the generated binding has enumeration members.

_WhiteSpace_enum
The enumeration used to constrain the whiteSpace facet

CF_whiteSpace
Specify the value-space interpretation of whitespace.

CF_minInclusive
Specify the minimum legal value for the constrained type.

CF_maxInclusive
Specify the maximum legal value for the constrained type.

CF_minExclusive
Specify the exclusive lower bound of legal values for the constrained type.

CF_maxExclusive
Specify the exclusive upper bound of legal values for the constrained type.

CF_totalDigits
Specify the number of digits in the *value* space of the type.

CF_fractionDigits
Specify the number of sub-unit digits in the *value* space of the type.

FundamentalFacet
A fundamental facet provides information on the value space of the associated type.

FF_equal
Specifies that the associated type supports a notion of equality.

FF_ordered
Specifies that the associated type supports a notion of order.

FF_bounded
Specifies that the associated type supports a notion of bounds.

FF_cardinality
Specifies that the associated type supports a notion of length.

FF_numeric
Specifies that the associated type represents a number.
