[sv-ec] covergroup option/type_option assignment

Section 20.6 of LRM mentions that options of a covergroup 
instance can be set procedurally.

Example:
--------
cg cg1 = new;
...
cg1.option.weight = 3;

In similar fashion, type_options for covergroup declaration
can also be set procedurally (section 20.6.1).

Example:
--------
cg::type_option.weight = 5;

Syntax 20-5 (page 321) and Syntax 20-6 (page 323)
of LRM, also describe the BNF for these assignment 
statements. But these rules donot appear in Annex  A
as well as in http://www.eda.org/sv/SV3.1a_bnf_no_footnotes.htm.

Any specific reason for this?
