Construct an NMTOKEN value from an item
value.
xs:NMTOKEN(item $value) => NMTOKEN
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.

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.
The following construct(s) refer to this construct:
