definition of chitin-binding proteins

Dear glycoscientists and protein scientists,

I am searching for a clear definition or a consensus among scientists on
the meaning of the term "chitin-binding proteins".

Raikhel et al. (Annu. Rev. Plant Physiol. Plant Mol. Biol. 1993
44:591-615) says that "chitin-binding proteins" denotes the family of
proteins containing one or more chitin-binding domains, where
chitin-binding domains are defined as the common structural motif of
30-43 amino acids (cysteine rich domain) found in e.g. hevein, WGA etc.

This is a very precise definition. Is it generally acknowledged? What
about glycosyl hydrolases such as chitinases? Would I be very wrong in
including these proteins in the term "chitin-binding proteins"? And what
about lysozyme? It can be argued that it is a chitin-binding enzyme
although chitin is perhaps not its naturally occurring substrate.

Any information, comments or references to literature is highly
appreciated!

Best regards
