Here are some of the specs:
Web Services Transfer (WS-Transfer). This specification describes a general SOAP-based protocol for accessing XML representations of Web service-based resources. https://www.w3.org/Submission/WS-Transfer/
Web Services Resource Transfer (WS-RT). This specification defines extensions to WS-Transfer. While its initial design focuses on management resource access its use is not necessarily limited to those situations. https://www.w3.org/Submission/WSRT/
I remember back when SOAP still had the upperhand against REST but just barely the W3C published a document where they showed how you could implement HTTP over SOAP to basically mass ridicule. Unfortunately can't find it anymore, but it was pretty funny.
