xsd:choice is natural and pervasive in vertical information modeling. It is
a fundamentally required structure, IMHO, and should be explicitly
supported by any serious tool. (Apache XML-Beans supports xsd:choice
without problems).

Please respond to Re: xsd:choice support

1) The JAX-RPC spec says that support for <choice> is not required for
automatic binding. But the JAX-RPC spec also requires that all valid
XSD constructs must be supported, and any construct that doesn't have
automatic mapping support must be mapped to SOAPElement.
2) No. Well, not really. You can replace the <choice> with a
<sequence>, and then specify that each element has minOccurs="0", but
there's no way to ensure that the message will contain one or the
other element and not both.
3) Workarounds: use SAAJ and process the XML manually or use a
different JAX-RPC implementation that does support <choice>
