So on read the base converts all relative URIs to the be grounded in the base. Is there any way to read a file with relative URIs and have the URIs remain relative?
On write the base converts all relative URIs to be grounded in the base in the output. Is there any way to write a file with relative URIs? In the preceeding example if the base were left out of the write would it make any difference in the output since all the URIs are absolute.
