$( Metamath-MathML Presentation Typesetting for set.mm, with MathJax rendering $)

$( The idea behind Metamath "structural" typesetting is to use the formula as a
   structure rather than a list of tokens. 
   Therefore a correspondence is provided for a list of schemes, rather than 
   for the tokens. A scheme consists in a metamath formula, possibly including 
   variables (e.g. ` A ` ), and a translation text, where variables can occur
   between # signs (e.g. #A# ).

	 Unification is done top-down, and checks for the schemes in sequence.
	 It stops as soon as a matching scheme is found, therefore specific schemes
	 shall be listed first, and generic ones last.

   This is used here for presentation MathML, but the same could be used for
   any translation.

	 In this version, 
	 - by default brackets are present in class infix operations ( A F B ).
	 - they are removed in cases where they can be omitted.
