I might be able to do it.  But this SOAP Data Model layer is
very important for interoperability between SOAP implementations
and between SOAP/other data model.  WSDL4R maps WXS(W3C XML Schema)
to SOAP Data Model.  There is also RDF-SOAP mapping.  NArray's n-dim
array is mapped to SOAP's n-dim array in SOAP Data Model as well.

I'm going to write YAML/SOAP bridge once YAML spec will be fixed.
SOAP Data Model -> YAML generator and YAML -> SOAP Data Model parser
are needed.  Using yamlrb, it won't be too hard to do.

$ ruby18 soapclient-xmlparser.rb
 10.846000   0.971000  11.817000 ( 22.007000)
$ ruby18 soapclient-rexmlparser.rb
 11.527000   1.011000  12.538000 ( 22.863000)
$ ruby18 soapclient-xmlscanner.rb
 13.329000   0.841000  14.170000 ( 24.347000)

xmlparser/0.6,5
rexml-stable/2.4.7
xmlscanner/0.2.2

Under ruby/1.6, xmlscanner is faster in some situation (depends on
marshalled data.)  Xmlscanner seems not to get along with 1.8.
