The cases you show don't appear to be terribly useful, but I think on
occasion this can be necessary to work around some arcane whitespace
rules in SGML or XML.  (Just look at the generated HTML; it uses this
technique throughout.)

It would be better if the tool could handle that, because sometimes you
want to use single quotes if the value contains double quotes.
