Re: shapes-ACTION-30: Send email to group with unclear "satisfied by's"

As discussed at the last meeting, we are extending the review period for 
the comparison of requirements and SHACL[1] until (at least) the meeting 
of Nov. 5. Since many of the requirements have a clear SHACL solution, 
for those who wish to save themselves time, here are the few 
requirements whose satisfaction is in question. Feel free to add any 
comments you wish. Note that some of these are actively under discussion 
at this time:

4.1.4 R4: Annotations
Constraints/shapes may incorporate extra information that does not 
affect validation. It shall be possible to search for constraints/shapes 
with particular extra information.

4.1.14 R11.5: Profiles
The language should include a notion of profiles, so that certain 
applications with limited features can only use certain elements of the 
overall language.

4.3.1 R6.3: Expressivity: String Operations
Some constraints require building new strings out of other strings, and 
building new URIs out of other values.

4.3.2 R6.4: Expressivity: Language Tags
Some constraints require comparing language tags of RDF literals, e.g. 
to check that no language is used more than once per property. Also to 
produce multi-lingual error messages.

4.3.3 R6.5: Expressivity: Mathematical Operations
Some constraints require mathematical calculations and comparisons, e.g. 
area = width * height.

4.4.5 R6.12: Expressivity: Checking for well-formed rdf:Lists
There shall be a concise construct for expressing that a list must be 
well-formed.

4.4.6 R6.13: Expressivity: Placing constraints on the values of rdf:Lists
There shall be a way of applying the constraints that we can express for 
normal

4.5.1 R8: Specialization of Shapes
It should be possible to specialize/extend shapes so that the 
constraints defined for a more general (super) shape also apply to the 
specialized (sub) shape. Sub-shapes can only narrow down, i.e. further 
constrain.
