Parsing and semantic interpretation are two distinct operations, both 
have merit.

A library should be able to parse the data stream without producing errors.

This is not an abstract issue for me, I had to fix bugs which threw 
serious exceptions because it could not determine if a value was a 
string or binary data (e.g. hexadecimal encoded string). When it made 
the wrong decision and tried to decode what it thought was hexadecimal 
encoding it produced a horribly malformed string which violated UTF-8, 
which then sent every library which was passed the string into the 
weeds. Which by the way would include any library which might try to 
interpret the semantic meaning of the string.

FWIW, I do not consider the ability to recognize a string as semantic 
interpretation. Semantic interpretation would be interpreting the 
string. Recognizing a string in a byte orientated data stream is parsing.
