Ian ThomasSubject: Help with XSD attributes
Author: Ian Thomas
Date: 30 Jul 2008 03:14 AM
I would appreciate some help with assigning schema data types to attributes in XSD.

Initially, I have tried for example

<xs:attribute name="TransactionCode" use="required" type="xs:NMTOKEN"/>

where I get the validation error

The 'TransactionCode' attribute is invalid - The value '@RPSX' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:NMTOKEN' - The '@' character, hexadecimal value 0x40, cannot be included in a name.

Similarly - also using type=xs:NMTOKEN - for '*MR' (name = RegisterCode) and for 'PMT 6' (name = ReferenceText).

What should be the correct schema data types for each of these attributes?

Hi Ian,
as the error message explains, a NMTOKEN can only contains the same characters allowed in a NameChar, that is letters and digits, plus '.', '-', '_', ':'
If your data must allow special character like @, * or spaces, you should define them to be generic xs:string types

Thanks, Alberto.
The "token" in NMTOKEN led me astray. The task is dealing with a small number (list) of what are essentially tokens or enumeration, but of course string is needed.
