Attributes shared by all elements simple none Presentation element set Attribute definitions normal bold normal italic MathML2 typographically-distinguished symbol attributes prefix infix postfix true false true false true false true false true false true false true false true false true false none solid dashed left right leftoverlap rightoverlap left right Presentation schemata with content Empty presentation schemata Presentation: general layout schemata Presentation layout schemata: scripts and limits Presentation layout schemata: empty elements for scripts Presentation layout schemata: tables Empty presentation layout schemata Presentation action schemata The following entity for substitution into content constructs excludes elements that are not valid as expressions. Presentation entity: all presentation constructs Content element set Attribute definitions Content elements: leaf nodes Content elements: specials Content elements: others Content elements: semantic mapping Content elements: constructors Content elements: symbols Content elements: operators Content elements: relations Content elements: quantifiers Operator groups Relation groups Content constructs: all Content constructs for substitution in presentation structures Recursive definition for content of expressions. Include presentation constructs at lowest level so presentation layout schemata hold presentation or content elements. Include content constructs at lowest level so content elements hold PCDATA or presentation elements at leaf level (for permitted substitutable elements in context) PCDATA or MathML character elements Content elements: tokens (may contain embedded presentation constructs) Content elements: special Content elements: other Content elements: semantics Content elements: constructors Content elements: operator (user-defined) Content elements: quantifiers Presentation layout schemata contain tokens, layout and content schemata. Presentation elements contain PCDATA or malignmark constructs. Browser interface definition Attributes for top-level element "math" Attributes for browser interface element scroll elide truncate scale The top-level element "math" contains MathML encoded mathematics. The "math" element has the browser info attributes iff it is also the browser interface element.
