At http://docs.fdsn.org/projects/source-identifiers/en/v1.0/definition.html#from-source-identifier-to-seed-nslc, in the "Mapping of SEED 2.4 codes ... From Source Identifier to SEED NSLC ... Channel codes" section, it says, > "Otherwise, there is no mapping when individual codes are greater than 2 characters." Should this not instead read as follows? > "Otherwise,` there is no mapping when individual codes are greater than 1 character."
