Working with a range of web services, I have found myself making extensive use of the LSIDs that are specific to each data source.  For example, for ITIS, I use the Ecsenius bicolor LSID: urn:lsid:itis.gov:itis_tsn:636326

For WoRMS, the LSID for Ecsenius bicolor is: urn:lsid:marinespecies.org:taxname:277652

For Atlas of living Australia the LSID for Ecsenius bicolor is:
urn:lsid:biodiversity.org.au:afd.taxon:99c29e7c-5b04-4e57-8e6b-82aa442a801a

Is there a GBIF LSID that can similarly be used as a unique identifier for a taxon? I have come across the various GBIF unique keys but these are not unique outside of the GBIF environment and within the Gaia Guide systems I am deciding how best to work with these, ensuring their uniqueness, alongside identifiers from other data sources.

Thanks again for your assistance.
