This looks useful as well for URIs.

The .desktop file spec says %U/%u is "URL", but there are combinations of 
possible protocols are too numerous. There are those programs that allow 
ftp & http; some provide smb support along with http, but not ftp; some 
may support fish and sftp, etc.

Therefore, if a certain program supports "IO backend XYZ", we can find 
that backend's .xml file and determine which URIs are supported. If the 
URL to be passed isn't supported, the file is downloaded and the 
application is watched for modifications to that file.
