AW: [xsd-users] Tree-Mapping and xsd:decimal several problems

[Forstner Michael]

Hi Boris,

thanks for your fast reply.
I'd really appreciate it if you could implement the custom CurrencyAndAmount type
for me.
Another problem is that after parsing a XML-File the internal double value
is still uninitialized. This "bug" would also be fixed with this custom type?

Thank you very much,
Michael
