Setting jaxb bindings for primates

Question

I have several schemes in which I create jaxb bindings that use liberal use xs:integer. I want these values ​​to be bound to long/ longrather than the default BigInteger. Unfortunately, I do not have the ability to change the schema. Adding a simple declaration to my bindings file causes it to xs:integerbind to longin all cases, even if this is the required value:

<jaxb:javaType xmlType="xs:integer" name="long" />

How can I get xs:integerto bind to a primitive when a field is required?
