The removal of jbossxb dependency from jbossws-spi component implies:
a) providing proper abstraction for retrieval of HandlersChainsMD and WebservicesMD (currently a JBossXB based object factory is accessed directly from metadata-common, AS, native / cxf stack)
b) providing StAX based parsers for webservices.xml, handlers-chain.xml, jbossws-cxf.xml (JMS stuff)
c) refactoring AS WSDescriptorDeployer which is currently a JBossXB based deployer, while we could have a simple parse deployer that installs the WebservicesMD obtained using proper call as described in a) [to be evaluate if it's worth spending time on this on AS6, given we're targeting AS7 for JBWS4]
