First, rough cut, of schemas for rspec and tickets, plus very simple

examples.

Note that these depend on the top schema from the assign directory.

protogeni/rspec/example-request-rspec.xml

+<?xml version="1.0" encoding="UTF-8" standalone="no"?>
+<!-- Example RSpec used to request for a ticket on a "regular" emulab node -->
+<!-- TODO: Do we want to include how long we're requesting it for?
+     Probably. -->
+ <rspec xmlns:"http://protogeni.net/resources/rspec/0.1">
+    <node uuid="00000000-0000-0000-0000-000000000002"
+          virtualization_type="raw">
+    </node>
+</rspec>
+
+<!-- Example RSpec used to request for a ticket on a VINI-like node -->
+<rspec>
