---++ Comments

The link to the source document seems to be broken. -- Main.PatrickLehmann - 2016-11-19

Fixed. -- Main.KevinJennings - 2016-11-21

The current wording is too vague and risks mutually inconsistent implementations. As it is, it would allow arbitrary cross referencing. However, it should either only allow back references to previously declared names or explicitly forbid cyclic references. -- Main.ThomasPreusser - 2016-11-21

How about adding "as long as the name in the interface declaration appears after the name in the interface definition" to the end of the sentence? Am open to other suggested wording as well. -- Main.KevinJennings - 2016-11-21

Going for back references only, I would suggest: 
A name that denotes an interface declaration in a generic interface list 
%RED%or a port interface list or a parameter interface list %ENDCOLOR%
may appear in %RED%a subsequent interface declaration within the 
interface list containing the denoted interface 
declaration. -- Main.ThomasPreusser - 2016-11-21

Agreed and updated in Version 2. -- Main.KevinJennings - 2016-11-21



Can we shorten the paragraph edited to:

A name that denotes an interface declaration in 
%RED%<del>a generic</del> an%ENDCOLOR% 
interface list may appear in 
%RED%<del>an </del>a subsequent%ENDCOLOR% interface declaration 
within the %RED%same%ENDCOLOR% interface list%RED.
<del>containing the denoted interface declaration.</del>%ENDCOLOR%

I am just wondering what ruling defines whether =Y1&#39;subtype= refers to the formal or rather the actual. This seems not to be clear at least for scalars.
