[web-annotation] Definitions of Specific Resources: Example

gsergiu has just created a new issue for 
https://github.com/w3c/web-annotation:

== Definitions of Specific Resources: Example ==
In my opinion the example for specific resources is inconsistent with 
the introduction text in the 
https://www.w3.org/TR/annotation-model/#specific-resources and with 
the WA Principles
https://www.w3.org/TR/annotation-model/#web-annotation-principles

Concretely, The introduction text says:
While it is possible using only the constructions in the core data 
model described above to create Annotations that reference parts of 
resources by using Fragment URIs, there are many situations when THIS 
IS NOT SUFFICIENT. For example, even a simple circular REGION of an 
image, or a diagonal line across it, are NOT POSSIBLE. 
.......
For example, if the Target of the Annotation is a circular region of 
an image, then the SpecificResource is the circular region, it is 
described by a SELECTOR, and is also associated with the source Image 
resource. 

1. The first issue I see is that the selector is not representend in 
the example .. as stated in the text above:
{
  "@id": "http://example.org/anno12",
  "@type": "Annotation",
  "body": {"@id": "http://example.org/comment1"},
  "target": {
    "@id": "http://example.org/region1",
    "@type": "SpecificResource",
    "source": "http://example.org/image1"
  }
}

2. According to the text in the WA Principles I would expect that one 
of the specific constraints must be present in the representation of 
Specific Resources:
-- The resource with these constraints is a separate resource from the
 Annotation, Body or Target, and is called a SpecificResource.
-- The SpecificResource refers to the source resource and the 
constraints that make it more specific.  

According to my understanding one of the following contraints must be 
present, otherwise is not a specific resource but a regular resource. 
Am I right?

 The types of additional specificity that are available:
--    State: Describe the desired representation of the source 
resource for the Annotation
--    Selector: Describe the desired segment of the source resource 
for the Annotation
--    Style: Describe the style in which the source resource should be
 presented for the Annotation
--    Scope: Describe the scope in which the source resource applies 
for the Annotation
--    Role: Describe the role that the source resource plays for the 
Annotation
