Friends!
How can the characteristics on the site and in 1C meet the requirements of the YML format? In particular, the moment https://yandex.ru/support/partnermarket/param.html
is of interest , where the characteristic has a unit of measurement. I did not find this in the Bitrix standard configuration. With 1C sign is bad. I will be glad to useful links and thoughts on this matter.

Answer 1

Option 1: write the unit of measure in the property description.
Option 2: create a separate property for the unit of measure.
Of course, all this will need to be processed correctly later in the unloading script.
