== | == Operator dictionary and heuristic rules for the operator form == | ||
Many operator properties affecting stretching are provided by the MathML Operator Dictionary. We should upgrade our dictionary to [http://www.w3.org/TR/MathML3/appendixc.html the one given in MathML3], where a lot of new entries are added and several properties modified. Also, the form infix/postfix/prefix is used to determine the properties of an operator. Hence, we need to implement the [http://www.w3.org/TR/MathML3/chapter3.html#presm.formdefval heuristic rules to determine the form] of an operator. | |||
[fred] The operator dictionary uses [http://hg.mozilla.org/mozilla-central/rev/4f08c0415dad the new syntax of MathML3] | |||
See {{bug|562460}} | [fred] Our private "direction" property is [http://hg.mozilla.org/mozilla-central/rev/16fd52fea1aa available for any operators] | ||

There are specific stretchy rules for [http://www.w3.org/TR/MathML3/chapter3.html#id.3.2.5.7.3 embellished operators] that should be implemented. | |||
