Name
xs:simpleType(global definition) — Global simple type declaration that can be referenced within the same schema by other schemas.

May be included in: xs:redefine, xs:schema
Description
Global user-defined simple datatypes are defined directly under the
xs:schema document element (or redefined using
xs:redefine) outside of the scope of any specific
content model. They can be referenced through their qualified name in
the same schema or by any other schema that has included or imported
this schema.
Like local simple datatypes, these are defined by derivation from
other simple datatypes (either predefined by W3C XML Schema or other
user-defined datatypes) using one of the three derivation methods
available for simple types: xs:restriction to add
new constraints to a datatype, xs:list to define
lists of values, and xs:union to perform the union
of the lexical spaces of several datatypes).
The name attribute is unqualified since the
datatype is considered to belong to the target namespace of the
schema in which it is defined. During a reference, the prefix that
has been defined for this namespace needs to be added.
Although simple datatypes are considered to belong to the target namespace of schema in which they are defined, they can be referenced ...
