Hi James,
You are right with the version negotiation but if you want to avoid troubles in
real life you should not trust that it works as supposed. But in your case
Mapserver behaves as it should. Browser do not know how to negotiate and
Mapserver sends WFS 1.1.0 GetCapabilities as an answer to your request which
lacks the version. 1.1.0 is the highest version that your Mapserver supports
and thus the response is correct.
In an attachment is a minimal mapfile for WFS 1.1.0 which emits no warnings
into GetCapabilities. It works with the states.shp shapefile which comes with
the demo data when you download Geoserver. Compare with your own mapfile and I
believe that you will find what breaks it. At least you use a non-existing
metadata in "WFS_OWS" "EPSG:4326"
Tested with Mapserver 7.0-beta and WFS 1.0.0, 1.1.0, 2.0.0, and without
"&version=".

So as I understand it to answer the original question, is there anything wrong
with the config, the answer here is no, and the error message is indeed in
error!
MapServer is expecting a version number in the request, so the error message
should perhaps reflect this facet.
However both the WFS 1.0.0 and WFS 1.1.0 tell me that the version parameter is
optional, so Mapserver shouldn't have this expectation.
For example:
Web Feature Service Implementation Specification, Version: 1.0.0
OGC 02-058
12.2 Request
...
The service attribute is described in section 7.8. The version attribute,
unlike the normal case, is not mandatory since a client application may not
have apriori knowledge about what versions a server may support. The client and
the server will need to apply the rules of version negotiation as described in
Section 6.2.4.
...
and
Web Feature Service Implementation Specification, Version: 1.1.0
OGC 04-094
6.2.4 Version number negotiation
An OWS Client may negotiate with a Service Instance to determine a mutually
agreeable specification version. Negotiation is performed using the
GetCapabilities operation [sec. 13] according to the following rules.
All Capabilities XML must include a protocol version number. In response to a
GetCapabilities request containing a version number, a web feature service must
either respond with output that conforms to that version of the specification,
or negotiate a mutually agreeable version if the requested version is not
implemented on the server. If no version number is specified in the request,
the server must respond with the highest version it understands and label the
response accordingly.
Cheers
James
