WARNING: Cannot find matching target Code(s)

Hi, 

While converting back a few XLIFF to... XLIFF (as they're generated by WPML), I came across several warnings, each one similar to:

WARNING: Cannot find matching target Code(s) id='2' originalId='' data='<x-br id=2/>' in TU tu15_sf15_tu1
 Segment: "<br class="xliff-newline" /><br class="xliff-newli..."
WARNING: Cannot find matching source Code(s) id='1' originalId='' data='[#$tu15_sf15_dp1]' in TU tu15_sf15_tu1
 Segment: "[#$tu15_sf15_dp1]<br class="xliff-newline" /><br c..."
WARNING: Cannot find matching target Code(s) id='2' originalId='' data='<x-br id=2/>' in TU tu16_sf16_tu1
 Segment: "<br class="xliff-newline" /><br class="xliff-newli..."

Source format was XLIFF files as spit out by WPML (with CDATA, wrong segmentation and exposed tags) and I converted them to "proper" XLIFF using the XML Stream filter.

Translation was done in OmegaT.

Any hints for solving these warnings?

TIA,

Marco
