XML : Preserving Space in an XML Document - JAXB

I have an XML document that is similar to the example below:

  <letter>    <to>A</to>    <from>B</from>    <subject>Email Notification</subject>    <heading>Reminder</heading>     <content xml:space="preserve">Thanks        Regards     </content>  </letter>    

When I'm using JAXB to unmarshall the XML Message the space is not preserved, so the Java string variable to hold the content removes the spaces, inspite of having the xml:space="preserve" attribute.

Is there any way to retain the space in java, does the JAXB binding support this ?
