function RulesAbstractPlugin::variableInfoAssertions

Returns asserted additions to the available variable info.

Any returned info is merged into the variable info, in case the execution flow passes the element. E.g. this is used to assert the content type of a node if the condition is met, such that the per-node type properties are available.
