Synopsis

<xs:attribute
           default        = xs:string
           fixed          = xs:string
           form           = ( “qualified” | “unqualified” )
           id             = xs:ID
           name           = xs:NCName
           ref            = xs:QName
           type           = xs:QName
           use            = ( “prohibited” | “optional” | “required” ) : “optional”
           {any attributes with non-schema namespace}

Description

This element serves two different purposes and has two different content models for these two purposes: it can either be a reference to a globally defined attribute or it can be a local attribute definition. These options are mutually exclusive.

When used as a reference to an attribute, the ref attribute must contain the qualified name of the attribute (with its namespace prefix).

When used as a local definition, the definition is done by assigning a simple datatype to the attribute. This assignment can be done either by reference, using the type attribute to refer to a simple datatype by its qualified name, or inline, by embedding the definition of the simple type (xs:simpleType element) within the xs:attribute element.
