To be discussed with Jordi. https://sentinels.copernicus.eu/web/sentinel/technical-guides/sentinel-3-olci/processing-baseline

<sentinel3: processingBaseline>PB_ID.xxx.yy.zz </sentinel3: processingBaseline>

<PB_ID> is unique and has as fixed format with 7 alphanumeric characters.
The definition of xxx.yy.zz version is the following:
xxx : baseline collection (starting from 002, 003 or 004 depending on the chain)
yy : minor changes in IPF or in static ADF (starting from zero for new baseline collection)
zz: changes in L0/PUG processing/task tables/PM or any other changes not expected to affect
the quality of the products (starting from zero when new baseline collection or minor change
is introduced). Only one PB_ID is applied on OLCI L1: e.g. in case of change of RAC or SPC
IPF which has no significant impact on product quality, zz shall be incremented.
