suggestion, 2.5 attribute checker

[Steven Carmody]

If I accidentally include a value in the attributes attribute on my 
AttributeChecker Handler definition that does NOT match an id value in 
my attribute-map file, then it appears that the AttributeChecker ignores 
that value ... if I'm configuring an SP, I might want to know that I 
made a mistake.

I don't see any relevant WARN/ERROR msgs in shibd log file.

And... can the AttributeChecker write to any log file ?

<Handler type="AttributeChecker" Location="/AttrChecker" 
template="attrChecker.html"
attributes="eppn displayName mail entitlement" flushSession="true"/>


thanks!
