[jdom-interest] Line feed parsing

[Gordon, Simon]

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="BASE64">ABCJDHFkdhewncSJDJ</tag>
<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_BASE64="ABCJDHFkdhewncSJDJ">
<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.
