AFAICS: no.
write
foo.attributes["bar"] = "aaa&apos;bbb&quot;ccc"

When an XML parser receives XML that is not well-formed (be it from an 
XML document, or as a string), it must report an error.
AFAICS: It must not try to recover by itself, for resons of 
interoperability.

The guesswork of HTML in cases like
<a>foo><bar<a/>
in something that XML avoids.

or suggest a method
escape_to_predefined_entities("aaa'bbb\"ccc")
-> "aaa&apos;bbb&quot;ccc"
