[jdom-interest] Line feed parsing

If you need to pass line-feeds or other non-valid XML characters** from
application to application, you should use some form of encoding like
BASE64. However, I would suggest moving this to element data so that the
encoding used can be passed as an attribute. For example:-
<tag encoding="TEXT">No non-XML characters in here</tag>
rather than using a variant of the attribute name to signal the encoding:-
<tag description_TEXT="No non-XML characters in here"/>
** XML character data is defined (section 2.4) as "any string of
characters...". See section 2.2 for the definition of a character and
section 2.3 for whitespace. Section 3.3.3 is where attribute value
normalization is described.

That's behavior mandated by the XML spec. Check the section on
attribute whitespace normalization.
