Re-generating code for only one xsd

[Spike Mulligan]

I'm working with Axis2(ADB) to generate server code for a WSDL with includes
to multiple schema files.  Particular files undergo regular extensions and
changes while others are much more stable.  My question is that when a
change occurs to a particular file am I able to regenerate only the code for
the schema that changed or can I only regenerate it for the whole WSDL?
