RE: [wsbpel-implement] The uploaded loan approval example

Yes, bpws should be defined as:

xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
(see Appendix D - XSD Schemas).

Examples in the spec also define it that way (see for example 16.1.2).

I think the spec uses "bpws" in many places as a shortcut for referring
to the namespace URI, without mentioning the fact that the "bpws" prefix
is arbitrary.
