The difference is that < is a legal character in C strings whereas 
NUL is not. Once the parser decodes that reference and tries to stick 
it in a string or stuff it in a database, all hell can break loose. 
Some languages are more  hell-resistant than others, but it's a big 
enough problem that it does need to be considered.
