[OAI-implementers] SOAP-PMH

[Roy Tennant]

For someone who is clearly too dense to get it (and not afraid to admit  
it), and for perhaps others who are in the same boat, could someone  
please describe the practical benefits of SOAP vs. OAI? That is,  
specifically what is enabled by SOAP that you cannot already accomplish  
using OAI? I've scanned the referenced paper for evidence and am still  
wondering. Thanks,
Roy Tennant
