There appears to be a consensus on how to handle two encodingStyle issues [1] (and
replies).
[1] http://lists.w3.org/Archives/Public/www-ws-desc/2002Jun/0178.html

1. Value of the encodingStyle attribute.

Everyone agrees that we should restrict the value of the encodingStyle attribute to be
either empty (for literal) or a single URI (for encodings like SOAP encoding). This is
approach taken in SOAP 2.2.

Dietmar  [2] further suggested that we reference the definition of this attribute from
the SOAP 1.2 envelope schema. We should discuss this suggestion further. On the
surface, it seems reasonable. I assume that the only place where this attribute appears
is in the SOAP binding extension schema, in which case it seems reasonable to import
the SOAP envelope schema. I assume that we'll need a SOAP binding schema for each
version of SOAP, i.e. that if SOAP changes, then we will probably have to update the
binding. Therefore it is OK to import the schema for the version of SOAP we are binding
to.

2. Where can you put the encodingStyle attribute.

There is general agreement that we need more flexibility in where we put the
encodingStyle attribute, i.e. people feel that encodingStyle might change in different
parts of the message. Limiting the attribute to the <body> element is too restrictive.
Jean-Jacques [3] says that SOAP 1.2 only allows the attribute on header blocks, body
blocks, and fault details (and all their descendents). Jean-Jacques [4] suggested that
it would be sufficient to allow encodingStyle to be specified on each message block
(and presumably also fault detail) but not their descendants. i.e. each block has a
single encodingStyle. This seems like a good compromise.
