Hi Lera and all,
Yes these have been my changes in order to reduce duplication of translations, which is what <embed> and <embedvar> is used for.
With that particular example, we had 'ImageMap' as regular text in all module main0102.xhp files, which meant that 'ImageMap' was being translated 4 or more times, as the help page title is 'ImageMap Editor'. So using <embedvar>, i eliminated having this duplication.
I dont see an issue that translators would need to place the translated word for ImageMap in the necessary position. Example in Russian:
"Редактор <variable id=\"imagemap_part_title\">Сенсорного изображения</variable>"
