 # Commented TSV
 
-Commented TSV builds on Typed TSV and allows for more flexibility in the format by including line comments. They are kept distinct so that some applications of it can take advantage of the extra flexibility, while others can stick with the more restricted Typed TSV format.
+Commented lines start with a '#' character at the beginning of the line. Unescaped '#' characters are not allowed on a line that does not start with a '#'. Any '#' characters in fields must be escaped.

-Commented lines start with a '#' character at the beginning of the line. Unescaped '#' characters are not allowed on a line that does not start with a '#'. Any '#' characters in fields must be escaped. Any unescaped '#' after the start of a line are errors.
 
 Comments must be UTF-8 encoded text.
 
-Comments are associated with the record beneath them. If a comment appears at the top of the file, it is associated with the file as a whole.

 Comments after the last record are an error.

-Commented TSV files should have the .ctsv extension.
-
-## Extending the Commented TSV Format
-
-Because it can include comments, this format lends itself well to extension. For example, if we wanted to extend the type system to include physical units, we could do so like this:
-
-```
-# UnitsTSV V1.0.0
-id:uint32\tdatetime:string\tmeasurement1:m:float64\tmeasurement2:v:float64\tmeasurement3:1/s:float64
-```
-
-Note that extended formats must remain parseable by baseline parsers, hence we must include the base types after the new types.
-
-Extending formats may also have restrictions. For example, they could disallow record comments and only allow the file comment above the header.
-
-Extended formats may still use the .ctsv extension, though they could use a dedicated one as well.
