Thanks Monte, that works.

For the benefit of future thread-readers, some tips it took me a while to 
figure out:

a) The above linked doc from apple refers to adding a CFBundleDocumentTypes 
array to your plist.   In the plist for a MacOS application, a 
CFBundleDocumentTypes array can include CFBundleTypeExtensions array listing 
file extensions.  However, using that same array in the iOS plist doesn't 
work.  Instead, you need to add a UTExportedTypeDeclarations array to the 
plist, which links file extensions to UTTypeIdentifiers; then you can add the 
CFBundleDocumentTypes array with a CFBundleTypeName referencing the 
UTTypeIdentifier.

b) If you do all that - then the other bit you need to know is to handle the 
"urlWakeUp" message - that's where your iOS app will get the file reference. 
Fortunately, Monte introduced me to that message just a couple of days ago on 
a separate thread!
