constraining equations question

[Stephen Wechsler]

Hi all,
Can anyone answer this question for me?  Is a constraining equation (f
ATT) =c VAL satisfied, or not, in a case where the f-structure for the
root node does not contain the function f, but the 'orphaned'
f-structure for a lower node in the tree does contain f with the
feature [ATT VAL] ?  This is possible where a c-structure node fails
to pass up some information.
