The wiki has a raised kerb as any kerb greater than 3cm in height. Your
definition of a regular kerb is one greater than or equal to 10cm.  A
raised kerb is a barrier to wheelchair and others with mobility issues just
as one that is 10cm or higher. I'm not sure what is gained by adding
another classification since the ability to add kerb:height already exist.
I can see adding a comment to the wiki page stating that the typical height
of a raised kerb  is around 10cm - assuming there is some research stating
