Ok, then CDATA support implemented in Axl is a perfect match for you.

Ok. Current CDATA support implemented in Axl won't give you any problem
because, as you know, CDATA sections won't look at your strings but
still pays attention to special CDATA string termination "]]>". 

However, this will not be a problem because Axl library detects the
presence of such string to properly escape it so you can fully store raw
binary data (utf-8 bytes) without worrying about end user or external
application introducing such termination into your xml tree.

Fine Maik. Cheers!
