I started with adding an xmpp: url link, but now I think it would be better 
to add sth. more generic than an xmpp link, just add,
The target attribute is used to decide whether to open the link in a new 
window or in the current window. For type 4 it defaults to _new, and for the 
rest of the types it defaults to _self.
The value stored in e.g. jabberid SkyPublicExtendedPersonAttributes of a 
person is used together with the corresponding urlpatterns from the 
OGoExtendedUrlAttributesMap Default.

 so I changed the patch to be able to define arbitrary link types via 
OGoExtendedUrlAttributesMap Default, for example:

        OGoExtendedUrlAttributesMap = (
            {
                type = 3;
                urlpattern = "mailto:%@";
            },
            {
                type = 4;
                urlpattern = "%@";
            },
            {
                type = 20;
                urlpattern = "xmpp:%@";
            },
            {
                type = 21;
                urlpattern = "fish://%@";
            },
            {
                type = 22;
                urlpattern = "imaps://%@";
            }
        );


SkyPublicExtendedPersonAttributes = (
            {
                key = jabberid;
                target = "_self";
                type = 20;
            },
            {
                key = anotherurl;
                target = "_new";
                type = 4;
            }
)

the ordinary url type is of type 4 (or has an attribute href) and email is 
type 3, 
I changed SkyObjectField.m to consider everything above 19 as a special link 
type, defined in OGoExtendedUrlAttributesMap, together with a definition of 
email and url type.

So this is not yet working for objects using LSWObjectViewer.m, should I add
the same there too? I am not sure whether it is really needed there.

kind regards
Sebastian
