Syntax

xs:NMTOKEN(item $value) => NMTOKEN

Description

This is a constructor function that takes an item value as argument and returns a value of type xs:NMTOKEN. If the argument is a literal, then the literal must be a valid lexical form of its type.

As specified in the respective section of the W3C recommendation XML Schema Part 2: Datatypes, a value of type xs:NCName denotes an XML name token, as defined in the XML 1.0 recommendation. It is derived from the type xs:token and the lexical form of xs:NMTOKEN is the set of all strings that match the production of Nmtoken. Practically, a value of type xs:NMTOKEN is the same as of type xs:Name with the only exception that it may not contain a colon.

Argument

$value	item value

Examples

The following queries generate valid values of type xs:NMTOKEN
```
xs:NMTOKEN("-header")
```
```
xs:NMTOKEN(":R2D2")
```
The following queries generate invalid values:
```
xs:NMTOKEN("+header")
```
The plus sign is not allowed in a name token.
```
xs:NMTOKEN("R2D2 C3PO")
```
It is interpreted as two tokens and thus cannot be a value of a single name token.
