During the F2F back in March [1], Charles had suggested [2] the following class for evidence:

<earl:evidence parsetype="Collection">
  <earl:ruleSet rdf:resource="ShadisOWL"/>
  <earl:Assertion rdf:resource="someAssertion"/>
  <earl:Assertion rdf:resource="anotherAssertion"/>

Basically, it is a collection with references to other assertions that together lead to a new assertion. For example, an assertion claiming conformance to WCAG 1.0 priority 1 could point to all the individual assertions that this claim is based on.

The earl:ruleSet was introduced to allow pointing to a rule set. For example, a set of OWL constraints that have to be met for the evidence clause to be true. However, I think we will be opening ourselves to a whole lot of complications with this.

On tomorrow's teleconference I'd like to go over the following:
* Refining the class and discussing the earl:ruleSet property
* Agree on where to put it (directly in an assertion vs result)
* Approve it to be added to EARL 1.0 Schema in the next update
