XML in a Nutshell, 3rd Edition

Name

xs:Name

Synopsis

xs:Name is a subtype of xs:token that is restricted to legal XML 1.0 names. In other words, the value must consist exclusively of letters, digits, ideographs, and the underscore, hyphen, period, and colon. Digits, the hyphen, and the period may not be used to start a name, although they may be used inside the name. These are all legal values of type xs:Name:

• G127

• _128

• Limit

• xml-stylesheet

• svg:rect

• 

• 亰

Constraining facets that apply to xs:Name are length, minLength, maxLength, pattern, enumeration, and whiteSpace.

XML 1.1 names that are not legal XML 1.0 names are not allowed. At the time of this writing, the schema working group has not yet decided how or when to update the schema specification to account for the changes in name rules in XML 1.1. They may issue an erratum to the schemas specification, or they may wait until Version 1.1 of the W3C XML Schema specification is published.
