RE: [sv-bc] nested modules under generate construct

Yet 26.2 says,
"A generate block may not contain port declarations, parameter
declarations, specify blocks, or specparam declarations. All other
module items, including other generate constructs, are allowed in a
generate block".

Looking at the BNF, it appears that module, program, and interface
declarations and timeunit declarations are also not allowed in
generates. whereas the BNF does appear to allow parameter declarations,
although the quoted sentence forbids them. In the 1364-2005 BNF,
parameter_declarations were in non_port_module_declaration, with the
other items not allowed in generate blocks, whereas in the 1800-2005
BNF, parameter_declarations moved to
package_or_generate_item_declaration.

	Daniel,
	 
	You are correct that the current BNF does not allow design
element declarations to be generated.
	 
	I don't know if this restriction was on purpose, but I don't see
why the allowed generation of type declarations (for example, class
declarations) would be relevant to the issue.  You can declare a type in
a procedural block, too.

	IEEE1800 BNF forbids to put nested module declaration under
generate:
	 
	module m;
	    parameter p = 9;
	    generate if (p)
	        module mm;
	        endmodule
	    endgenerate
	endmodule
	 
	This was done on purpose or this was just missed.
	IE class declaration is allowed to be used in generate clause.
