Tweak existing XLIFF files according to translation team feedback
The XLIFF file miss
xml:space="preserve", a trans-unit must look like:
<trans-unit id="mlang_labels_tablabel" xml:space="preserve"> <source>Webpages and databasecontent</source> </trans-unit>
Each trans unit must have the
xml:space="preserve"attribute, this is needed by Pootle to avoid some weird problem.
An other point, please add
product-name="package.name" to the file element, we use it for v4 core, and it's sometime useful to have this information in the XLIFF.
