Implicit nets in analog and digital behaviour

Hi all,

Currently implicit nets are not allowed in the behavioural part of the analog syntax and is allowed only in the structural part.

ie.

child chd1(a,b,c); // "c" need not be declared electrical and is a implicit net
analog begin
  V(c) <+ 5; // "c" cannot be an implicit net and has to be declared.
end

However, in the digital side of things i am told that Verilog 1364 allows implicit nets as part
of behavioural statements.

Can anybody clarify why there is a discrepancy here? Should digital nets take the "default_discipline" for resolving the net domain?

cheers,
Sri
