ETSI TS 103 255 specifies the Abstract Test Suite (ATS) for the conformance test suite for using XML Schema with TTCN-3, as defined in ETSI ES 201 873-9 [1].

The objective of the present document is to provide a basis for conformance tests for TTCN-3 tools supporting "Using XML Schema with TTCN-3" extension [1]. The conformance test suite should give a high probability of standard conformance with respect to TTCN-3 tools from different vendors. In the present document only using XML Schema with TTCN-3, specified in ETSI ES 201 873-9 [1] have been considered but not the core language [9], tool implementation (see ETSI ES 201 873-5 [i.1] and ETSI ES 201 873-6 [i.2]), language mapping (see [i.3] and [i.4]) and language extension (see e.g. ETSI ES 202 781 [i.5], ETSI ES 202 784 [i.6] and ETSI ES 202 785 [i.7]) aspects. The test notation used in the ATS attached in a zipped file is in TTCN-3 and it is part of the present document.

Annex A provides the Tree and Tabular Combined Notation (TTCN-3) part of the ATS.

Annex B provides the Partial Implementation Extra Information for Testing (PIXIT) Pro forma of the ATS.
