Answer 1

I looked into the XSD structure that you have posted - and find that you have not used complex type that you have defined for the month , Insteqad of handling it on java code you can mention that all in XSD , and also the minOccur on month - element in your complex type is missing . Please use any standered XSD to java generator , it will do all the java file generation task for you

The convention are as follow - 

MinOccur = 0 --> the element can be abscent in input , and can be present

MinOccur = 1 --> the element must be there in input
(but if you use it, then your java generated member will be of list type - list of ENUM for Int )

If you don't write MinOccur in attributes - then it makes the element mandatory , ( then you java generated member will be of simply ENUM for int )


MaxOccur = 1 --> minimum one element can be there in input 
(but if you use it, then your java generated member will be of list type - list of ENUM for Int )


MaxOccur = unbound --> only one element can be there in input 
(if you use it, then your java generated member will be of list type - list of ENUM for Int )
