The WebCGM WG thank you for your comments on WebCGM 2.0.

The WebCGM WG has the following responses to your comments:

RESPONSE to Comment 1:
Agreed, we will fix it.  Thanks for catching this.  The <title> elements 
should match the text that immediately precedes the horizontal rule at 
the top of each chapter.

RESPONSE to Comment 2:
Originally we had considered that both generic and specific were 
appropriate, as described in CharMod C063 [1] (and its immediately 
preceding comment).  Upon further discussion, the WebCGM WG believes 
that generic alone suffices.  The References will be changed to contain 
only the generic reference.

RESPONSE to Comment 3:
The basic reason is "legacy".  WebCGM 2.0 is an upgrade of WebCGM 1.0, 
which is a profile of ISO CGM:1999.  In ISO CGM:1999 (and :1992, :1987 
before it), the default is isolatin1.  Because the default is implicit 
(nothing in the CGM file declares it), and because of the mechanism 
which ISO CGM specifies for changing to a non-default character encoding 
for a metafile instance, in fact it would be technically ill-specified 
(i.e., unimplementable) for a profile such as WebCGM 2.0 to prescribe 
that the implicit default is other than isolatin1.

We agree that WebCGM 2.0 should use the proper terminology, "character 
encoding", where ever possible.  In some places it is not possible, such 
as the proper names of ISO CGM:1999 elements (e.g., "CHARACTER SET 
LIST").  But we will make appropriate changes in the descriptive, prose 
parts of the profile.
