It seems clear that you asked one question, then completely changed
the parameters - it's always best to be clear about the complete
intent up front, in order not to waste peoples time proposing
solutions which don't meet your requirements.

In terms of dynamically updating the XSD, I'd at least consider a
secondary validation URL which provides the modified rule on the fly 

e.g the modified rule is dynamically generated from content held in a
DB and processed by requesting a specific but variable URL on a web
server.

XSI include http://www.w3schools.com/schema/el_include.asp (or in SOAP
terms, www.---.com)  is one
way I could see that working

Each time the schema is loaded (assuming the parsing code is set to
not cache includes) then it should request a fresh copy of the
included schema. 

The included XSD schema elements need not necessarily come from a
static file source. The include should presumably specify whatever
regex is required.

You could potentially also use XSL on a base schema document per
request, so it's modified on the fly that way prior to validation
being performed using the generated schema.

Again you'd want to ensure the validator always requested a fresh
instance rather than caching it client side.

In PHP (my favourite scripting language) I'd be making SOAP calls with
the WSDL_CACHE_NONE parameter set, to ensure a fresh copy of the WSDL
was requested for each time the SOAP object was instantiated.
