Parts of XSD 1.1 Used by OWL

The OWL 2 specification explicitly depends on certain parts of the XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes, enumerated below. The OWL 2 Candidate Recommendation (11 June 2009) is based on the XSD 1.1 Candidate Recommendation (30 April 2009), so OWL 2 implementations are also implementations of the following parts of XML Schema 1.1:

• From Section 2, the general framework for defining a datatype system, in particular:
  • 2.1 Datatype
  • 2.2 Value Space
  • 2.3 The Lexical Space and Lexical Mapping (excluding 2.3.1 Canonical Mapping)

• From Section 3, the definitions of the following datatypes (but excluding any facets not listed below):
  • 3.3.1 string
  • 3.3.2 boolean
  • 3.3.3 decimal
  • 3.3.5 float
  • 3.3.6 double
  • 3.3.8 dateTime
  • 3.3.16 hexBinary
  • 3.3.17 base64Binary
  • 3.3.18 anyURI
  • 3.4.1 normalizedString
  • 3.4.2 token
  • 3.4.3 language
  • 3.4.4 NMTOKEN
  • 3.4.6 Name
  • 3.4.7 NCName
  • 3.4.13 integer
  • 3.4.14 nonPositiveInteger
  • 3.4.15 negativeInteger
  • 3.4.16 long
  • 3.4.17 int
  • 3.4.18 short
  • 3.4.19 byte
  • 3.4.20 nonNegativeInteger
  • 3.4.21 unsignedLong
  • 3.4.22 unsignedInt
  • 3.4.23 unsignedShort
  • 3.4.24 unsignedByte
  • 3.4.25 positiveInteger
  • 3.4.28 dateTimeStamp

• From Section 4.3, the definitions of the following constraining facets:
  • 4.3.1 length
  • 4.3.2 minLength
  • 4.3.3 maxLength
  • 4.3.4 pattern
  • 4.3.7 maxInclusive
  • 4.3.8 maxExclusive
  • 4.3.9 minExclusive
  • 4.3.10 minInclusive

• From Section 5.4, the conformance requirements for partial implementation of lexical spaces.

OWL 2 also implicitly depends on the following parts of XSD 1.1 Datatypes, as they are used in the above mentioned sections:

• From Appendix D, auxiliary functions used in the definitions of value spaces.

• Parts of Appendix E relevant to the above mentioned datatypes, e.g., the definitions of the lexical to value mappings.

• From Appendix G, the definition of regular expressions.
