RE: [SPAM] Issue with IgnoreUncidedEndpoint in LocationTemplate-1G

We just talked about adding "nillable or optional or have a default
value" to the proposal. I would suggest we give an order to this:

        "...any element not cited in tje {http location} property MUST
        be defined in the schema as nillable, or as not nillable but
        with minOccurs=0, or not nillable and with minOccurs>0 but with
        a default value."

In this way, the reconstituting side will, depending on the schema,
stick it in as nil (if it's nillable), or omit it (if it's optional) or
stick it in as empty, in this order. This assumes the reconstituting
side knows the schema, but they are expected to know the WSDL so we're
ok I think.
