What do you mean with that?  Example?

>      elsif($mixed eq 'STRUCTURAL')
>      { # mixed_element eq STRUCTURAL is handled earlier
>        panic "mixed structural handled as normal element";

It is much simpler. The ::Translate contains this code:

    my $mixed = $self->isTrue($node->getAttribute('mixed') || 'false');
    undef $mixed if $self->{mixed_elements} eq 'STRUCTURAL';

Which means: if 'STRUCTURED', then simply ignore the mixed attribute ;-)
But it may need to be smarter in future versions.  So: makeMixedElement()
cannot be called in this case.

Probably not.

I did not write XML::LibXML::Simple::XMLout(), because I think it is a
bad idea in the first place; you cannot DWIM correct output generation.
But if you go into the dark areas, then why not use XML::Simple's version?
