Generate Java classes from XML Schema with restrictions using JAXB

Question

By the use of the command line tool 'xjc' for example, it is possible to create Java classes from an existing XML Schema.

I've tried that with a simple XML Schema before:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">

 <xs:element name="employee" type="employee"/>

 <xs:complexType name="employee">
  <xs:sequence>
    <xs:element name="name" type="xs:string" minOccurs="0"/>
    <xs:element name="salary" type="xs:double"/>
    <xs:element name="designation" type="xs:string" minOccurs="0"/>
    <xs:element name="address" type="address" minOccurs="0"/>
  </xs:sequence>
  <xs:attribute name="id" type="xs:int" use="required"/>
 </xs:complexType>

 <xs:complexType name="address">
  <xs:sequence>
    <xs:element name="city" type="xs:string" minOccurs="0"/>
    <xs:element name="line1" type="xs:string" minOccurs="0"/>
    <xs:element name="line2" type="xs:string" minOccurs="0"/>
    <xs:element name="state" type="xs:string" minOccurs="0"/>
    <xs:element name="zipcode" type="xs:long"/>
  </xs:sequence>
 </xs:complexType> 
</xs:schema>

But when I add a definition which has some restrictions, the restrictions will be just ignored. For example:

<xs:element name="Temperature" type="myTemperature"/>
<xs:simpleType name="myTemperature">
 <xs:restriction base="xs:double">
  <xs:minExclusive value="-273.15"/>
 </xs:restriction>
</xs:simpleType>

or

<xs:element name="age">
 <xs:simpleType>
  <xs:restriction base="xs:integer">
   <xs:minInclusive value="0"/>
   <xs:maxInclusive value="100"/>
  </xs:restriction>
 </xs:simpleType>
</xs:element>

All the restrictions like minInclusive, maxInclusive, maxLength, totalDigits, etc. will be ignored. Is there a way to include this restrictions in the creation of the Java classes from the XML Schema?

@lreeder Definitely not duplicate. The linked question wants to do things the other way around (Java -> XSD), this one wants XSD -> Java. — vbence, Feb 27 '14 at 09:29
@vbence, I'm not sure why you are saying this. The linked question provides a schema, and the java code that it *wants to generate* from the schema, so it is also XSD->Java. Both questions want to generate restrictions in java from restrictions defined in the schema. — lreeder, Mar 02 '14 at 18:15
It's not easy to parse, but OP in the linked question says "I want it to get converted **to** Java code", not "**from** Java code". — lreeder, Mar 02 '14 at 18:25
