Yes, I actually followed this example, which I found in one of the mails:

Hence, what I did are the following steps (with some minor modifications 
like --hxx-suffix .h --cxx-suffix .cpp):

/xsdcxx cxx-tree --std c++11 --generate-serialization 
--generate-xml-schema  --hxx-suffix .h --cxx-suffix .cpp --custom-type 
double=double --custom-type "decimal=long double" --hxx-epilogue-file 
xml-schema-epilogue.h xml-schema.xsd/

/xsdcxx cxx-tree --std c++11 --root-element-last  --hxx-suffix .h 
--cxx-suffix .cpp --extern-xml-schema xml-schema.xsd 
--generate-serialization vtk-unstructured.xsd/

/xsdcxx cxx-tree --std c++11 --root-element-last  --hxx-suffix .h 
--cxx-suffix .cpp --extern-xml-schema xml-schema.xsd 
--generate-serialization vtk-punstructured.xsd/

Here, the 'xml-schema-epilogue.h' is exactly the same as found in 
'custom-double.zip'. Also the files 'decimal.h', 'decimal-parsing.h', 
'decimal-serialization.h', 'double-parsing.h' and 
'double-serialization.h' are unchanged except from changing the extension.
