Minutes:

Treating analysis function:
   - should it be constant expression or analog operator or system 
function (or an event?)
   - It is not a constant expression because it changes values during a 
simulation for ic and nodeset
   - We dont want to treat it as analog operator or system function, 
then it becomes difficult to use in constant condtionals or document the 
restrictions for other analog operators
   - Dont want to treat as event as there is no else clause on events. 
Too late to change this aspect and deviates from digital a lot
   - Create a class of functions to handle analysis functions 
separately. Similar to the cyclic pure functions in VHDL? Graham will 
incorporate this as part of the syntax which will be included in chapter 
5 and any other relavent sections

Switch branch syntax:
   - Switch branch will not be detailed as a separate syntax in the BNF. 
Its more of a semantic object which is defined as part of section 5.1.6.
   - Not much of change to chapter 5.1.6 is required from the latest 
version.
   - The restrictions of usage of analog operators should be (and is 
documented) as part of chapter 4.
   - Geoffrey is going to add another example to value retention section

Updates to chapter 5:
   - Graham will post new syntax with analysis function, which will be 
put into chapter 5
   - Sri will remove the syntax sections for contributions and indirect 
contributions from chapter 5 and incorporate as part of chapter 6 where 
all statements are defined
   - Once this is done, the sections in chapter 5 will be reorganized to 
make it more readable eg. probably move value retention near switch 
branch details etc.

Next week:
   - Review of chapter 2, lexical section as we ran out of time this week.

cheers,
Sri
