 Add the following rules to check when validating Symbol Definitions:

  * Check for non-existent symbol parameters
  * Check that at least one geometry usage context has been specified.
  * If using resource data for an image graphic, verify the resource data
 specified checks out
  * If using inline PNG base64 content for an image graphic, verify the
 content checks out as an image
  * If using a composite rule in a layer definition, verify that symbol
 references point to valid symbol definitions
  * If using a composite rule in a layer definition, verify that the
 overrides specified are for symbol parameters that actually exist
  * If using a composite rule in a layer definition, warn if the symbol
 definition has usage contexts that are irrelevant against the layer's
 feature source (eg. Line Usage context specified in a point-only feature
 source)
