| Name | shipTo | XML 1.0 Name type |
| QName | po:USAddress | XML Namespace QName |
| NCName | USAddress | XML Namespace NCName, i.e. a QName without the prefix and colon |
| anyURI | http://www.php.cn/,http://www.php.cn/ | |
| language | en-GB, en-US, fr | valid values for xml:lang as defined in XML 1.0 |
| ID | XML 1.0 ID attribute type, see (1) | |
| IDREF | XML 1.0 IDREF attribute type, see (1) | |
| IDREFS | XML 1.0 IDREFS attribute type, see (1) | |
| ENTITY | XML 1.0 ENTITY attribute type, see (1) | |
| ENTITIES | XML 1.0 ENTITIES attribute type, see (1) | |
| NOTATION | XML 1.0 NOTATION attribute type, see (1) | |
| NMTOKEN | US,Brésil | XML 1.0 NMTOKEN attribute type, see (1) |
| NMTOKENS | US UK,Brésil Canada Mexique | XML 1.0 NMTOKENS attribute type, i.e. a whitespace separated list of NMTOKEN's, see (1) |
Notes: (1) To retain compatibility between XML Schema and XML 1.0 DTDs, the simple types ID, IDREF, IDREFS, ENTITY, ENTITIES, NOTATION, NMTOKEN, NMTOKENS should only be used in attributes. (2) A value of this type can be represented by more than one lexical format, e.g. 100 and 1.0E2 are both valid float formats representing "one hundred". However, rules have been established for this type that define a canonical lexical format, seeXML Schema Part 2. (3) Newline, tab and carriage-return characters in a normalizedString type are converted to space characters before schema processing. (4) As normalizedString, and adjacent space characters are collapsed to a single space character, and leading and trailing spaces are removed. (5) The "g" prefix signals time periods in the Gregorian calendar. | ||
