I have tried many variations of inserting a hyperlink (in calc) for a notes://
url.  These are neither recognized as urls when typed in, nor are processed when
inserted as a hyperlink.  By processed I mean it seems they do not get passed on
to the browser or configured notes application.   

The feature I am requesting is that this behavior be changed so that notes://
uri's are recognized.

The following may or may not be helpful:

I did some rudimentary searching of the code base from
anoncvs.services.openoffice.org, and found that hltpbase can not find a matching
scheme, from urlobj.  Now I am not entirely positive that hltpbase is the right
place to start my search, but it seems reasonable enough.  I then went and
looked at urlobj and see that it lists several schemes:

#define INET_FTP_SCHEME "ftp://"
#define INET_HTTP_SCHEME "http://"
#define INET_HTTPS_SCHEME "https://"
#define INET_FILE_SCHEME "file://"
#define INET_GOPHER_SCHEME "gopher://"
#define INET_MAILTO_SCHEME "mailto:"
#define INET_CID_SCHEME "cid:"
#define INET_NEWS_SCHEME "news:"
#define INET_POP3_SCHEME "pop3://"
#define INET_LDAP_SCHEME "ldap://" 
....
and many more.  However there is no scheme for notes://.  There are of course
other places in this file I can see would need to be modified IF this is in fact
the correct place to add an additional protocol.
