However, with tools like WebEQ Equation Editor , or the Page Wizard utility for converting from WebTeX to MathML, it is generally not necessary to directly edit much MathML by hand. In MathML there are two kinds of elements . These elements can have other data in between the start and end tag, such as text, extended characters, or other elements. These elements have just one tag, which looks like a hybrid between a start and an end tag. All MathML elements accept a few attributes , and some accept a dozen or more.
Attributes generally specify additional information about the element.
Each attribute has a name and a value. Attribute values must always be enclosed in quotes. In XML, either double or single quotes are permitted. For technical reasons involving how browsers work today, WebEQ requires that single quotes be used. The proper format for a given attribute is listed in the presentation reference section.
