[xsd-users] abstract type and its c++ equivalent

[Klima Georg]

Hello Boris,

thank you, thats exactly what I do: packaging all xsd generated code into a static library.
This also explains why that dynamic cast helps, it "forces" linkage, that would otherwise be omitted. - My best guess!

Hi Georg,

This means that there is no C++ type corresponding to the XML Schema type specified with the xsi:type attribute or used in a substitution group. Can you make sure that you have compiled all your polymorphic types as such (--polymorphic-type-all should take care of this) and also that you actually compile and link all the generated .cxx files into your application. One common situation where this might not happen is if you package the generated code into a static (.a) library.
