Can you say two nouns are in apposition if the second one only refers to part of the first?
I do not think this could be considered an example of an appositive noun. I believe the second noun phrase in the sentence must completely identify the first noun in order for the two to be in apposition. For example, see the sentences below, at

"The pages curled and damp" does not identify the "few books" that "I" found.
