RE: [sv-bc] e-mail ballot: respond by Dec 3, 8am PST

I agree with Brad, though I don't think these are critical.

Also, the footnote now says,

"A package_import_declaration in a module, interface, program ANSI style
header shall be followed by a parameter_port_list or
list_of_port_declarations, or both."

"ANSI style header" is an informal term which in my opinion does not
belong in a BNF footnote. I would simply write it in the brute force
form:

"A package_import_declaration in a module_ansi_header,
interface_ansi_header, or program_ansi_header shall be followed by a
parameter_port_list or list_of_port_declarations, or both."

This is also not critical.
