[jira] [Commented] (XERCESC-2198) Support xsd 1.1 in C++

    [ https://issues.apache.org/jira/browse/XERCESC-2198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17116718#comment-17116718 ] 

Scott Cantor commented on XERCESC-2198:
---------------------------------------

I really don't see how there's any possibility of this being done unless you have a patch to contribute, and even then the risk to the code base would require more review resources than exist.

If your industry really needs this code base to be viable, you would have to supply a number of experienced C++ programmers to maintain it. It's barely on life support now.

> h3. The Request
> Please support xsd 1.1 in the C++ based Xerces.
> Around the web it has been suggested that you don't have plans to support it because most uses are experimental. The following case is different:
> h3. Background
> The Association of Automobil Industry in Germany ([VDA|http://vda.de/], Verband Der Automobil Industry) has recently developed an open standard file format for describing welds and joints for widely used for automobile manufacturers. The format is called xMCF ('extended master connection file'). This format has been designed to share information across CAD, CAE and CAM teams using a single file.
> During the past few years, I have been involved in the development of this format. We have used xsd 1.1 to describe the schema. This is [the gitub repository|https://github.com/economidis-nick/createXSDforxMCF/tree/master/V3.0r1] where the standard has been developed.
> The standard is nearly complete, and most software vendors that build tools for the automotive companies would like to use C++ library in order to test the validity of a xml file.
> h3. Rationale
> So far we have used the *XercesJ* implementation to build a xMCF validator for the test suite of the repository. But the software vendors would like a C++ version of it so that they can incorporate the validator in their software, which in this industry is typically C++.
> They do not want to depend on Java, because Java's future depends on the company that owns/runs it.
