Hi,
So a server will be required to guess the correct datastore until it
finds the right one that matches the action instance?
<action>
<top>
<list1>
<key>10</key>
<do-test>
<datastore>candidate</datastore>
</do-test>
</list1>
</top>
</action>
The server will guess the datastore in some proprietary order and parse
instances of /top/ and /top/list1. Then it finds the <do-test> action
and parses the input to get to the datastore and find out the real datastore
to use. If the server guessed wrong, then it reparses the <action> against
the requested datastore. Hopefully the schema trees match up.
Will vendors do all the extra work required to support this sort of thing?
I doubt it.
