Identified changes for section 11

Hello All,

Before I start to make changes to the chapter 11 (directives), I have 
summarized the major changes to chapter that I can see occurring. Please 
review.

 Since 1364-2005 has introduced the `begin_keyword and `end_keyword 
directives, how should the predefined __VAMS__ and __VAMS_ 
COMPACT_MODELING__ macros should be handled differently in Verilog-AMS 
LRM 2.3?  Should the `begin_keyword and `end_keyword directives be 
extended to include Verilog-AMS specific versions or subsets?


- section 11 (Introduction)
    - Change references from 1364-1995 to 1364-2005
    - Expand list of AMS directives to include directives from the 
1364-2005 section. Refer directives unaffected by AMS to 1364-2005, all 
others refer to section numbers
- section 11.1: `default_discipline
    -  No change
- section 11.2 `default_transition
    - No change
- section 11.3 `define and `undef
    - Collapse section down to a reference to 1364-2005, except for the 
paragraph referring to __VAMS__?
- section 11.4 `ifdef, `else and '`endif
    - Remove section and refer to 1364-2005 in the introduction
- section 11.5 `include
    - Remove section and refer to 1364-2005 in the introduction
- section 11.6 `resetall
    - Remove section and refer 1364-2005 in introduction
- section 11.7 Predefined Macros
    - update4 references to 1364-1995 and version fo the Verilog-AMS LRM
- `celldefine and `endcelldefine
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `default_nettype
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `line
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `timescale
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `unconnected_drive and `nounconnected_drive
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `pragma
    - No AMS specific behavior is present and therefore no section needs 
to be added
- `begin_keywords and `end_keywords
     - extend the 1364-2005 version specifier to include specific 
versions of the Verilog-AMS LRM or subsets of keywords (i.e. analog or  
compact modeling)?
- ` default_analog
    - is this multiple analog block directive going to be added into the 
language?

Regards
Graham
