L.6.1.5 Delimiters

Delimiters consist of opening and closing delimiting characters (such as parentheses, braces, brackets, and vertical bars), and an element contained inside. If two or more elements are contained within delimiters, separating characters are used.

Delimiters can grow to the height of the object they contain. For example, parentheses could grow quite

enclose this multi-row matrix:

. Or, at ) 1

the user’s discretion, they can maintain their height regardless of the content inside, as in

Delimiters have a single child object, the base argument, which can be used multiple times in the object to signify that a separator character is to be used. For example:

If the separator character is not specified in XML, the vertical bar is used.

Example:

Example XML:
