[jdom-interest] UNDECLARED_ATTRIBUTE

[Elliotte Rusty Harold]

The Attribute class defines integer constants for the various attribute 
types including a default of UNDECLARED_ATTRIBUTE

    protected int type = UNDECLARED_ATTRIBUTE;

In my opinion, this is incorrect according to the XML 1.0 specification, 
http://www.w3.org/TR/REC-xml#sec-attribute-types , "All attributes for 
which no declaration has been read should be treated by a non-validating 
processor as if declared *CDATA*." (The restriction to non-validating 
processors here is IMO an erratum in the spec which I just reported to 
the editors.) I think we should delete the UNDECLARED_ATTRIBUTE field 
and use CDATA as the default attribute type.

On a related note, should we perhaps be using the type-safe enum pattenr 
here instead of int constants?
