feature -- Properties

	verbatim_marker: STRING
			-- Delimiter used to mark the beginning and end of the
			-- verbatim string.
			-- If `empty', no marker was used.

	is_indentable: BOOLEAN
			-- Is verbatim string indentable, i.e. can all lines be prepended
			-- by the same white space without changing string value?
			-- Normally, indentable verbatim string is enclosed in '[' and ']'.
			-- Non-indentable verbatim string is enclosed in '{' and '}'.
