Comment about UUID uniqueness seems missing...

I think it is reasonable to take it as "practically unique" [1]

I presume PDAL uses Boost.Uuid [2] implementation (as libLAS does), thus

"either guaranteed to be unique (...) or it is extremely likely to be
unique" [2]

[2] http://www.boost.org/libs/uuid/index.html
