Newbie question: fixed attribute & restriction

[Guy Crets <guycrets@hotmail.com>]

Hi All,

Is it allowed to have an attribute within a restriction?  If I 
read/understand the Schema 2001 spec well, it is.

However, Xerces 1.4.2 reports an error when parsing (validating) the 
document underneath.  "Error: URI=null Line=5: Schema error: Anonymous 
complexType: ct-props-correct.2: The type 'xsd:string' is a simple type.  It 
cannot be used in a derivation by RESTRICTION for a complexType."  When 
using extension instead of restriction, all goes well.

Thanks for your feedback.  Regards, Guy Crets (Belgium)
