Neither. The reason you don't see AccessType.NONE and AccessType.PUBLIC
is because they have been
introduced since Early Draft 2 but the later version of the
spec/javadocs are not available (but
will be available soon). By the way it is going to be
AccessType.PUBLIC_MEMBER not
AccessType.PUBLIC.

There are other alternatives to using @XmlTransient - even with Early
Draft 2 version.
a. set the default to @XmlAccessorType(AccessType.PROPERTY)
move the annotation to the getter/setter from the field to the property.
b. set the default to @XmlAccessorType(AccessType.FIELD)
the property is not serialized by default.
c. Both a and b are in Early Draft 2. This one will be in post Early
Draft 2.
The default will be @XmlAccessorType(AccessType.PUBLIC_MEMBER) which
means only public fields and properties are serialized by default.
Thus if you
put the annotation on the property there is no need to put
@XmlTransient on the
field itself since the field is private and won't be serialized by
default anyway.
d. This one will be available in the post Early Draft 2 version.
set default serialization to @XmlAccessorType(AccessType.NONE) which
means
neither fields nor properties are serialized by default; the
field/property has to be
explicitly annotated for it be serialized.
