Various XML constructs in inline content

[Yves Savourel <ysavourel@enlaso.com>]

Hi all,

Another aspect we have to address is the various XML constructs one can find in mixed content (comments, processing instructions, CDATA sections) and what are the processing expectation for them.

Here is my take:

-- comments

XML comments must be stripped out.
An XLIFF processor must strip XML comments (<!--...-->) found inside a content.
Any comment that need to survive processing needs to be set using the XLIFF notes mechanism.


-- Processing Instructions

XML processing instructions must be stripped out.
An XLIFF processor must strip XML processing instructions (<?...?>) found inside a content.
Tool-specific data should be set using XLIFF's extension mechanism.


-- CDATA sections

CDATA sections (<![CDATA[...]]>) are allowed, but on output they may be changed into normal escaped content by the processor agents.
An XLIFF processor must read properly CDATA sections inside an inline content, but it is not required to preserve the notation when writing out the document.


Any thoughts?
