a bad specification in defaultStyleProp

[Lofton Henderson <lofton@rockynet.com>]

All --

There is some confused language in the defaultStyleProp description.  It 
says:

"The defaultStyleProp element of the ACI is the mechanism defined to 
specify values for certain CGM attribute and control elements that are not 
present in the CGM file. If an cooresponding element is present in the CGM 
file, the default specification has no effect."

This is *NOT* what we want to impose on viewers.  The viewer would have to 
interpret and understand the entire metafile before it could decide whether 
to apply the default!

"The defaultStyleProp element is the ACI mechanism to specify default 
values for certain CGM attribute and control elements whose default is 
otherwise under-specified in CGM:1999 and the WebCGM profile.  This 
element, when processed at initialization time, will set default values for 
the applicable metafile elements.  If the contents of the metafile, upon 
interpretation, explicitly set the applicable metafile element (either via 
METAFILE DEFAULTS REPLACEMENT or via the element itself in the body of the 
picture), then that explicit intra-metafile setting supersedes the 
defaultStyleProp setting."

That wording encapsulates the stated purpose:  set under-specified 
defaults.  (For V1 files as well as V3/V4 files.)

Objections?
