well, yes and no.  the syntax of TDL is the constraining factor here,
not Lisp, strictly speaking.  but the single quote is a TDL operator,
so |lunghezza_d'onda_3| is not a valid identifier (using the pipes as
a kind of `quote mark' here).  |"_lunghezza+d'onda_n_3_rel"|, on the
other hand, is a valid TDL string, hence for the PRED value you could
actually go with that.  which might be nice, as we usually expect the
PRED to reflect the citation form (in `common' orthography).  as for
the identifier (of the lexical entry, in this case), there are a few
more characters, besides |+|, that are available for TDL identifiers,
e.g. |-|, |_|, or |*|.  these identifiers are fully grammar-internal,
so you should be free to invent a convention that makes sense here.
