When <facelets-processing> mode is set to jspx/xml, the JSF implementation should strip the CDATA section wrappers (ie. "<![CDATA[" and "]]>"). These wrappers should not be represented in the corresponding UIComponent tree or be passed through in the rendered content.
Currently, the CDATA section wrappers are removed, but this is implemented by removing the entire CDATA block, including any nested text content. This is not the desired behavior - ie. the text content itself should survive - only the CDATA wrapper constructs should be removed.
