ETSI ES 201 873-9 Using XML schema with TTCN-3 A short presentation of the status A short presentation of the status

Intention Get standardized, readable names for modules The structure in the namespace identifiers should be reflected in TTCN-3 module identifiers

History Originally no namespace mapping to module identifiers defined Standardized ATSs need clear definition! TT proposed adding standardized mapping rule Name mapping rules for XML names were reused by reference for the namespace mapping BUT: namespace can contain characters which are not allowed for XML names, e.g. „/“ Rule was not adapted SO: Examples demonstrate the real intention TT committed CR 5847 to correct this discrepancy http://t-ort.etsi.org/view.php?id=5847

Current status Discrepancy resulted in different interpretations of the standard in the tools INT STFs use the intended mapping 3GPP STF160 starts usage of XML and needs clarification NOW Example http://www.example.org/foo/bar Formal rule : http_www_example_orgfoobar Intended rule : http_www_example_org_foo_bar

Summary Intended rule provides best readability for the user Acceptance of TTCN-3 will be enhanced Adapt the rule according to the CR 5847 and the extension proposed by Ericsson Correct all examples without a namespace
