Hi Ben,
probably you are right, declaring that targetAttributeNode is used in a
wrong way in my usecase, I added it trying to understand why the lcv:class
attribute (declared as xs:anyType) was not encoded in GML. Probably, after
the patch to anyType handling I talk about in my email (that's the main
point of my issue, not the targetAttributeNode usage) it would work also
without it (I will try).
The main issue remains: is it correct to add handling of "primitive"
(simple) types to xs:anyType bindings and which approach seems better to
you, changing ComplexSupportXSAnyTypeBinding or its parent class
XSAnyTypeBinding?
Any hint is appreciated.
Thanks
Mauro Bartolomeoli
