<td colspan="5" class="print">issue was raised by 3GPP, see mail
discussion with Shicheng Hu:<br />
Hi Gyorgy and All<br />
 <br />
Thanks for the explanation. I understand better about the pros and
cons.<br />
 <br />
As you all know, the 3GPP conformance test suites are globally used for
the UE certification. There are two basic requirements<br />
 <br />
1. The test suites delivered by STF160 should be unique as the
standardised test suites.<br />
2. Copyrights of the test suites belong to ETSI and the other 3GPP
organizational partners.<br />
 <br />
Now, because of the two mapping options I have the following
problems.<br />
 <br />
1. The 3GPP test suites should be analysed by all existing tools. The
import XSD statement in the 3GPP test suites must be slightly adapted
for the mapping options, and the imported XSD modules must be replaced
with the mapped TTCN modules. Therefore, STF160 is no more in the
position to provide a "unique" delivery for the UE certifications. The
high risk is what happens if the UE to be certified passes the test with
one mapping option, but fails the test in another mapped option?<br />
 <br />
2. The explicit mapping option is relying on the tools and has
introduced a Copyrights problem. The generated mapped TTCN modules by
the tool (from the original XSD modules) is a piece of software. Its
copyrights are owned by the tool makers. ETSI has no copyrights on this
piece of TTCN codes. This is against the current copyrights principle
for the ETSI standards once a 3GPP delivery includes the mapped TTCN
modules generated by the tools. As you know, the copyrights have the
commercial implications.<br />
 <br />
3. On the top, there is a big tool interoperability problem with the
explicit mapping, supposing the Part 9 is correct. The mapped TTCN
modules generated by one tool cannot ne accepted by the others.<br />
 <br />
My preference is to stick the explicit mapping, despite of the technical
difficulties. Your comments are welcome.<br />
 <br />

Subject: RE: XSD import<br />
Hi Shicheng,<br />
<br />
It is not so straightforward. Both ways has their pros and cons. XSD
differs from the TTCN-3 type system significantly both in philosophy, in
concrete language components and ways of restricting and combining those
components. So, for example, if importing an ASN.1 type, it is
relatively straightforward how the equivalent TTCN-3 type would look
like, i.e. how to define the TTCN-3 instances of that type. It is far
not so easy for types, attributes and elements imported from XSD.<br />
<br />
So, the clear benefit of the explicit mapping is that the user can SEE
the generated TTCN-3 definitions that makes writing values and templates
more easy. Another benefit is, that â€“ if needed â€“ the user may tweak
the generated TTCN-3 types â€“ until the XML codec support the changes.
Of course, it also has drawbacks, e.g. the user need to take an
additional step to convert XSD to TTCN-3 modules, has to handle
additional files in its project and in the version control system and
shall not forget to re-generate the TTCN-3 modules if XSD is updated and
a more difficult tool implementation.<br />
<br />
And, if course, implicit mapping has its pros and cons. Pros are e.g.
the simpler handling of projects, less files, no forgotten updates etc.
and the list of cons are the missing features that were the benefits for
the explicit mapping â€“ so, more or less pros and cons are the opposite
as with the explicit mapping.<br />
<br />
So, I think, there is no ideal solution, just different ones with
different properties.<br />
<br />

Subject: XSD import<br />
<br />
Hi Gyorgy and All<br />
 <br />
I have an issue on XSD import in Part 9. Why does the standard allow the
implicit and explicitly import XSD modules as two options? An implicit
mapping makes much more sense.<br />
