slur from a tuplet to the outside

Hello, all --

I'm a newbie to Lilypond, but loving it so far (just over 24 hours); 
after almost a decade wrestling with Finale and a couple of years with 
the technically wonderful but totally corporationally frustrating Igor 
Engraver, it's great to see stunning output (the best I've ever seen!) 
from an open-source app...

Anyway, my specific question right now is this: I'm trying to draw a 
slur originating within a tuplet in one measure and terminating in the 
next measure, like so (example from my Igor engraving of the same 
piece):

I can't seem to get the correct syntax -- so far, this is the best I've 
done:

    %% m004
    \time 3/2
    { <<a' f''>>4\mf ef'' \times 2/3 {d''4-\tenuto\( af' bf'} b'8 e'?\> 
b? bf\!  } |
    %% m005
    \time 7/4
    <
        { af4\)\p \grace g8-( <<c' bf'>>2-\upbow-) <<d' 
cs''>>1-\downbow } \\
        { s2. \transparentStem g4 }
    > |

but I get a parsing error:

warning: can't find start of phrasing slur:
        { af4\
              )\p \grace g8-( <<c' bf'>>2-\upbow-) <<d' 
cs''>>1-\downbow } \\

warning: unterminated phrasing slur:
    { <<a' f''>>4\mf ef'' \times 2/3 {d''4-\tenuto\
                                                   ( af' bf'} b'8 e'?\> 
b? bf\!  } |

I think I understand the basic issue, but don't see how to overcome the 
problem -- any hints would be greatly appreciated!

Best regards,
Kieren.
