bug on CDataSection of batik SVGDOM ?

[Tonny Kohar]

hi,

The CDataSection of batik SVGDOM is splitted into multiple CDataSection
on each new line? is it a bug?

The problem occur when the SVGDom generated by batik is to be
serialized/writing back to text file. Because the result of serialized
is not the same with the loaded one due to different in CDataSection.
Batik itself also unable to open/load the result of serialization.

I attached the file to reproduce the problem.

Regards
Tonny Kohar
