You don't have to check the implementation, you can simply check the Org
syntax¹.
Blocks
Like greater blocks, pattern for blocks is:
#+BEGIN_NAME DATA
CONTENTS
#+END_NAME
NAME cannot contain any whitespace character.
[...] If it is “SRC”, it will be a “source block” [...]
DATA can contain any character but a new line. It can be ommitted,
unless the block is a “source block”. In this case, it must follow the
pattern “LANGUAGE SWITCHES ARGUMENTS”, where SWITCHES and ARGUMENTS
are optional.
