switch( (bVisible << 1) | bPrintable )

case 0: eDisplayToken = XML_NONE; break;
case 1: eDisplayToken = XML_PRINTER; break;

The idea just seems to be that the default behaviour for that tag is
that if no xml-display attribute is set, then the importer is to act as
if xml-always was present. So its a little size optimization to not
export the attribute if it equals the default value.

For clarity, if you wanted, you could change the initial
XMLTokenEnum eDisplayToken = XML_TOKEN_INVALID;
to
XMLTokenEnum eDisplayToken = XML_ALWAYS;
and change
if( eDisplayToken != XML_TOKEN_INVALID )
to
if( eDisplayToken != XML_ALWAYS )
