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.
