In cases where a start element has both attributes and non-empty textual
value, we have to create a bogus property; we will use this as
the property name.

Name used for pseudo-property used for returning XML Text value (which does
not have actual element name to use). Defaults to empty String, but
may be changed for interoperability reasons: JAXB, for example, uses
"value" as name.
