An e-Learning application has a database of quiz questions, some of which contain MathML. The MathML comes from multiple sources, and the e-Learning application merely passes the data on for display, but does not have sophisticated MathML analysis capabilities. Consequently, the application is not aware whether a given MathML instance is pure presentation or pure content markup, nor does it know whether the instance is valid with respect to a particular version of the MathML schema. It therefore places the following data formats on the clipboard:
| Flavor Name | Flavor Content |
| ___________ | _____________ |
| MathML | <math xmlns="http://www.w3.org/1998/Math/MathML">...</math> |
| Unicode Text | <math xmlns="http://www.w3.org/1998/Math/MathML">...</math> |
An equation editor on the Windows platform is able to generate pure presentation markup, valid with respect to MathML 3. Consequently, it exports the following flavors:
| Flavor Name | Flavor Content |
| ___________ | ______________ |
| MathML Presentation | <math xmlns="http://www.w3.org/1998/Math/MathML">...</math> |
| Tiff | (a rendering sample) |
| Unicode Text | <math xmlns="http://www.w3.org/1998/Math/MathML">...</math> |
A schema-based content management system on the Mac OS X platform contains multiple MathML representations of a collection of mathematical expressions, including mixed markup from authors, pure content markup for interfacing to symbolic computation engines, and pure presentation markup for print publication. Due to the system's use of schemata, markup is stored with a namespace prefix. The system therefore can transfer the following data:
| Flavor Name | Flavor Content |
| ___________ | ______________ |
| | |
| | <math |
| | xmlns="http://www.w3.org/1998/Math/MathML" |
| public.mathml.presentation | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" |
| | xsi:schemaLocation= |
| | "http://www.w3.org/Math/XMLSchema/mathml4/mathml4.xsd"> |
| | <mrow> |
| | ... |
| | </mrow> |
| | </math> |
| | |
| | <math |
| | xmlns="http://www.w3.org/1998/Math/MathML" |
| public.mathml.content | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" |
| | xsi:schemaLocation= |
| | "http://www.w3.org/Math/XMLSchema/mathml4/mathml4.xsd"> |

| | <mrow> |
| | <apply> |
| | ... content markup within presentation markup ... |
| | </apply> |
| | ... |
| | </mrow> |
| | </math> |
| | |
| public.plain-text.tex | {x \over x-1} |
| | |
| | <math xmlns="http://www.w3.org/1998/Math/MathML" |
| | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" |
| public.plain-text | xsi:schemaLocation= |

| | </math> |

A similar content management system is web-based and delivers MathML representations of mathematical expressions. The system is able to produce MathML-Presentation, MathML-Content, TeX and pictures in TIFF format. In web-pages being browsed, it could produce a MathML fragment such as the following:
<math xmlns="http://www.w3.org/1998/Math/MathML">
<semantics>
<mrow>...</mrow>
<annotation-xml encoding="MathML-Content">...</annotation-xml>
<annotation encoding="TeX">{1 \over x}</annotation>
<annotation encoding="image/tiff" src="formula3848.tiff"/>
</semantics>
</math>
A web-browser on the Windows platform that receives such a fragment and tries to export it as part of a drag-and-drop action, can offer the following flavors:
| Flavor Name | Flavor Content |
| ___________ | ______________ |
| | |
| |
| MathML Presentation | <math xmlns="http://www.w3.org/1998/Math/MathML"
| | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| | xsi:schemaLocation=
| | "http://www.w3.org/Math/XMLSchema/mathml4/mathml4.xsd">
| | <mrow>
| | ...
| | </mrow>
| | </math>
| |
| |
| MathML Content | <math
