Your schema allows for multiple elements in the wildcard content. That
is, your could have something like this:

<m2m: primitiveContent xmlns:m2m="http://www.onem2m.org/xml/protocols">
  <m2m:ae xmlns:m2m="http://www.onem2m.org/xml/protocols">
    ...
  </m2m:ae>
  <m2m:ae xmlns:m2m="http://www.onem2m.org/xml/protocols">
    ...
  </m2m:ae>
  <m2m:ae xmlns:m2m="http://www.onem2m.org/xml/protocols">
    ...
  </m2m:ae>
</m2m:primitiveContent >

I am not sure what you want to do with that. Serializing them all will
create a "multi-root" document which is not a valid XML.

In any case, what you need to do is serialize primitiveContent to DOM.
Then you can iterate over its child elements and serialize them one
at a time. Or, alternatively, you could iterate over the wildcard
content and just serialize each element -- will probably be more
efficient. Examples and the FAQ on the Wiki have some sample code
for doing this.
