If the target is an expression in a formula, you must first turn the expression into a target. Select the

expression and choose Create target from the Links menu to create an id attribute for the target

expression.

14.3. More about MathML

14.3.1. Browsers compatibility

Several browsers support MathML:

• Internet Explorer with the MathPlayer plugin

• Firefox and other Gecko-based browsers

• Opera since version 9.5

It is necessary to use the .xml suffix to be sure that XHTML documents are managed as XML. Without

this suffix some browsers do not display correctly documents that include mathematical expressions. It is

also recommended to use the utf-8 charset for all XML documents.

By default Amaya adds the XHTML 1.1 plus MathML 2.0 doctype at the beginning of the document.

This doctype is not mandatory but it is useful:

• to validate the document,

• to generate alphanumerical entities (like ∫) for mathematical symbols in the source code.

Otherwise mathematical symbols are coded like any other unicode character.

Unfortunately, this doctype is not supported by many browsers. So it could be necessary to remove this

doctype with the Amaya command: Tools/Change doctype/Remove the doctype.

IE uses the pmathml.xsl transformation style sheet and a plugin to display the MathML code included

in XHTML documents. Amaya adds automatically a link to that transformation style sheet, but the author

must store a copy of this style sheet (pmathml.xsl) in the local directory of the document.

14.3.2. Known issues

• Amaya implements only the Presentation part of MathML 2.0, not the Content Markup part.

• A few Presentation tags are not entirely available: mglyph, maction

• All presentation elements and attributes are available, but only the following attributes are

rendered on the screen: display, alttext, mathvariant, mathsize, mathcolor,

mathbackground, fontsize, fontweight, fontstyle, fontfamily, color,

linethickness, numalign, denomalign, bevelled, notation, lquote, rquote,

lspace, rspace, largeop, movablelimits, subscriptshift, superscriptshift,

form, width (mspace only), height (mspace only), depth (mspace only), align,

rowalign, columnalign, frame, framespacing, displaystyle, side, rowspan,

columnspan, rowspacing, columnspacing, rowlines, columnlines.

• The class, id, and style attributes are available, with the same semantics as in (X)HTML:

you can associate CSS styles with MathML elements (class and style attributes) and a

MathML element can be the target of a link (id attribute).

• Amaya uses the STIX fonts to render mathematical symbols, but currently not all symbols are

supported.
