"Name" Datatype Values and Representations
This section describes the built-in datatype 'Name' designed to support XML element and attribute names. 'Name' datatype is derived from 'token' by restricting the value set according the XML 'Name' specification.
The second datatype derived from "token" is "Name", which is designed to support "Name" strings define in the XML 1.1 specification.
"Name" is a datatype derived from "token" datatype by limiting values to those satisfy the following pattern defined in XML 1.1:
NameStartChar::= ([:A-Z_a-z\xC0-\xD6\xD8-\xF6\xF8-\u02FF]| [\u0370-\u037D\u037F-\u1FFF\u200C-\u200D]| [\u2070-\u218F\u2C00-\u2FEF\u3001-\uD7FF]| [\uF900-\uFDCF\uFDF0-\uFFFD\u010000-\u0EFFFF] NameChar ::= (NameStartChar|[-.0-9\xB7\u0300-\u036F\u203F-\u2040]) Name ::= NameStartChar(NameChar)*
"Name" strings are defined to be used as element names and attribute names in XML documents. According the above definition, we can use non-English characters in "Name" strings. In other words, we can use Chinese characters as XML element or attribute names.
Similar to "language" datatype, input lexical representations of "Name" datatype will be validated and evaluated in 2 steps:
Here is a sample XSD document that defines a sub element <Name> to use "Name" values:
<?xml version="1.1"?> <!-- Name_datatype_test.xsd - Copyright (c) 2002-2013 HerongYang.com. All Rights Reserved. --> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="Name_Datatype_Test"> <xs:complexType> <xs:sequence> <xs:element name="Name" type="xs:Name" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>
Here is a sample XML document that contains <Name> elements to test that definition:
<?xml version="1.1"?> <!-- Name_datatype_test.xml - Copyright (c) 2002-2013 HerongYang.com. All Rights Reserved. --> <Name_Datatype_Test> <!-- 6 valid "Name" elements --> <Name>name_datatype_test</Name> <Name>complexType</Name> <Name> html </Name> <Name> xs:token</Name> <Name> head </Name> <Name> 头</Name> <!-- 5 invalid "Name" elements --> <Name>complex Type</Name> <Name> (html)</Name> <Name> xs+token</Name> <Name> 1st_head</Name> <Name>  </Name> </Name_Datatype_Test>
Run the JDK tool XsdSchemaValidator.java again, you will see 5 groups of errors for the last 5 invalid elements. But error messages do not provide the "Name" string pattern
