Draft- Ch.9 "informative subsection"

Here is my Draft- Ch.9 "informative subsection" on ACI File Association.

-------------------------------------------------------------------------------
ACI File Association recommendations

Since the goal of the ACI file is to improve interoperability between the various providers of WebCGM 2.1 viewers, these recommendations for associating an ACI file with a WebCGM 2.1 viewer are included.

It is recommended ACI file have the extension ".aci" (all lowercase) on all platforms.  

To convey to a WebCGM 2.1 viewer the location of an ACI file, an environment variable name WebCGM_ACI_File is defined.  This environment variable could be set at the time of the viewer installation or modified by a user. On Windows this should be System environment variable that would apply to all users. 

For example-  
   WebCGM_ACI_File=c:/Documents and Settings/All Users/Application Data/CGM Open/WebCGM

If not feasible for a viewer to set an environment variable during viewer installation or users are prohibited from doing so due to security policies that are becoming commonplace in large organizations, then the viewer should provide an alternative method for users to specify the ACI file search path, for example in a viewer preferences or configuration menu.
