Subject: undeclare_prefix bug as i think (not tested)

XML-NamespaceSupport v1.09 I researched sources you XML::NamespaceSupport 1.09 version and found interesting place. I think there is bug. The chunk from code: sub undeclare_prefix { my $self = shift; my $prefix = shift; return unless not defined $prefix or $prefix eq ''; return unless exists $self->[NSMAP]->[-1]->[PREFIX_MAP]->{$prefix}; This line (return unless not defined $prefix or $prefix eq '';) is very strange. I have tested such test: $prefix = 'alex'; print "alex\n" unless not defined $prefix or $prefix eq ''; After i see 'alexl'. Thus teh prefix will be alex or other string, we will get return execution. Thus undeclare_prefix will not work properly. If $prefix = '' i will not see "alex" string. And if $prefix will be undef i don't see "alex" too (i think this is incorrect too) My suggestion: To change this line to return if not defined($prefix); This code will work if the prefix will be any string or '';
