Re: [xliff-seg] Pro/Cons on xml:tm methods

[Andrzej Zydron <azydron@xml-intl.com>]

Hi Yves,

Thank you for your comments and pointing out the practical issues involved 
concerning paired tags and sub-flows. <tm:tu> elements cannot split xml 
elements. In the instance where an end of a sentence is contained within a mixed 
content element the overriding rule is that of XML integrity. Sub-flows can be 
handled in one of two ways:

1) The sub-flow remains within its parent <tm:tu>.
2) The sub-flow can be separated out into a new trans-unit with a marker 
inserted to allow for the correct placement on merging.

Sub-flows are not normally a problem as they have been handled in the initial 
extraction into XLIFF.

Best Regards,

AZ
