trailing space required for dimensionless quantities?

[VladimirAlexiev]

If I write "1"^^ucum:dimensionless in the LINDT playground, I get this warning:

Datatype format exception: "1"^^<http://w3id.org/lindt/custom_datatypes#dimensionless>

I have to write it with a trailing space: "1 "^^ucum:dimensionless.
Is the space really necessary? It seems to me it will be a simple matter to allow the user to omit it.

I don't think I will have the time to solve this issue in the near future though. Plus the current implementation is already quite old (fork of jena 3.4.0 when jena reach version 3.16.0)
