1 Scope ®
The present document defines the mapping rules for W3C XML Schema (as defined in [7] to [9]) to TTCN-3 as
defined in ETSI ES 201 873-1 [1] to enable testing of XML-based systems, interfaces and protocols.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI ES 201 873-1 [1], Recommendation
ITU-T X.694 [4] and the following apply:
alphabetical order: way of sorting the XSD names based on the code positions of their characters according to
ISO/IEC 10646 [i.4]
NOTE: During this sorting the group, plane, row and cell octets is considered, in this order. Names, starting with
a character with a smaller code position take precedence Among the names with identical first character,
names containing no more characters take precedence over all other names. Otherwise, names with the
second character of smaller code position take precedence, etc. This algorithm is to be continued
recursively until all names are sorted into a sequential order.
schema component: generic XSD term for the building blocks that comprise the abstract data model of the schema
NOTE: The primary components, which may (type definitions) or obliged to (element and attribute declarations)
have names are as follows: simple type definitions, complex type definitions, attribute declarations and
element declarations. The secondary components, which are obliged to have names, are as follows:
attribute group definitions, identity-constraint definitions, model group definitions and notation
declarations. Finally, the "helper" components provide small parts of other components; they are not
independent of their context: annotations, model groups, particles, wildcards and attribute uses.
schema document: XML document containing a collection of schema components, assembled in a schema element
information item
NOTE: The target namespace of the schema document may be defined (specified by the targetNamespace
attribute of the schema element) or may be absent (identified by a missing targetNamespace attribute of
the schema element). The latter case is handled in the present document as a particular case of the target
namespace being defined.
target TTCN-3 module: TTCN-3 module, generated during the conversion, to which the TTCN-3 definition produced
by the translation of a given XSD declaration

3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI ES 201 873-1 [1], Recommendation
ITU-T X.694 [4] and the following apply:
alphabetical order: way of sorting the XSD names based on the code positions of their characters according to
ISO/IEC 10646 [i.4]
NOTE: During this sorting the group, plane, row and cell octets is considered, in this order. Names, starting with
a character with a smaller code position take precedence Among the names with identical first character,
names containing no more characters take precedence over all other names. Otherwise, names with the
second character of smaller code position take precedence, etc. This algorithm is to be continued
recursively until all names are sorted into a sequential order.
