Issue
There are a few elements and attributes in MathML 2.0 that were not implemented in MathFlow 1.7-1.9. MathFlow 2.0 and later has better MathML 2 coverage and some MathML 3 coverage. Other elements behave slightly differently in MathFlow than the specification requires. Below, we've listed the known differences between standard MathML and the MathFlow implementations. If you find something not on this list, please contact us at support@wiris.com.
MathFlow 1.x
- MathML 3 not supported.
-
Plane 1 Unicode Characters Not supported in MathFlow 1.x. However, the alternative method of selecting these characters using the
mathvariantattribute (or setting the font style) is implemented to the extent that the MathFlow fonts permit. -
mo: The attributes
separatorandfencehave no effect.The default value forminsizeis 0 in MathFlow rather than 1 as described in the specification. - mglyph: Not implemented.
-
mstyle: The attributes
scriptsizemultiplierandscriptminsizeare ignored. Setting the value ofbackgroundtotransparenthas no effect. -
mmultiscripts: The attributes
subscriptshiftandsuperscriptshifthave no effect in MathFlow -
mtable: The
displaystyleattribute has no effect; use thedisplaystyleattribute in anmstylesurrounding the table. Thealignmentscopeattribute is not used in MathFlow -
maction: MathFlow supports the following action types suggested by the MathML 2.0 specification:
toggle,statusline, andhighlight. MathFlow also provides support for two additional action types:linkandmouseover. The namespaced attributesdsi:color,dsi:background,dsi:cue1,dsi:cue2, anddsi:hrefare used to pass action parameters not specified in MathML 2.0. - declare: Has no effect on rendering.
MathFlow 2.x
-
Linebreaking and indentation: MathFlow 2's support for MathML 3 linebreaking and indentation includes:
- Enhanced linebreaking in tables.
- Automatic linebreaking and alignment by operator.
- A Linebreak Attributes dialog which can be accessed from the Preferences menu.
-
Elementary math elements: MathFlow does not yet support
mstack,mscarry,mscarries,msgroup,msrow,msline, andmlongdiv. - Right-to-left: MathFlow does not yet support right-to-left editing & rendering.
-
mo: The attributes
separatorandfencehave no effect. The default value forminsizeis 0 in MathFlow rather than 1 as described in the specification. - mglyph: Not implemented.
-
mstyle: The attributes
scriptsizemultiplierandscriptminsizeare ignored. Setting the value ofbackgroundtotransparenthas no effect. -
mmultiscripts: The attributes
subscriptshiftandsuperscriptshifthave no effect in MathFlow -
mtable: The
displaystyleattribute has no effect; use thedisplaystyleattribute in anmstylesurrounding the table. Thealignmentscopeandgroupalignattributes are not used in MathFlow - maction: MathFlow does not support the menu or tooltip actions from MathML specification. MathFlow uses the namespaced attributes dsi:color, dsi:background, dsi:cue1, dsi:cue2, and dsi:href to pass additional action parameters not specified in MathML 2.0/3.0.
