RFC 7483 describes entity name searches. As I understand it, the searches
are to use the same rules as for domains and nameservers: a prefix,
followed by at most one wildcard, followed by some number of domain labels.
I have been assuming that there will be no domain labels for entity names,
so it would just be a prefix search.

My coworker has pointed out to me that this isn't necessarily so useful.
You could search for contacts by first name, but not by last, and so on. Is
that in fact what you have in mind with these sorts of searches?

And only names? There is no provision for searching entities by address,
etc.?

Also, what is to be done with non-ASCII characters? Should the names be
folded to ASCII values, so that a search for "Bohm" will match an O with an
umlaut? Or is that not correct behavior? Is this to be a case-insensitive
search? What about whitespace? We didn't see clear directives in the RFC,
but maybe we missed them.

Thanks.

Brian
