27. Web Services Interoperability Issues  Type Encoding – explicit typing of parameters (eg., "xsd:integer" vs "xsd:int" )  SOAPAction Header – Some implementations support both SOAPAction values of "" and null, while others do not  Message Parameters – Some toolkits have the ability to set multiple out params, while most toolkits can process one and only one out param – Order of parameters for return types on the client side.  SOAP Envelope – Encoding style, envelope level or body level? – Namespace qualification – IDs and Href

28. Web Services Interoperability  SOAPBuilders – Grassroots organization – Canonical set of tests, testing interoperability on live implementations – soapbuilders@yahoo.com  WS-I.org – Industry initiative for Web services interoperability – Open to any organization committed to Web services – Promote and accelerate adoption, deployment of Web services
