license = ProprietaryEULA **Equation Editor**is aformula editor developed byDesign Science that allows users to construct math and science equations in aWYSIWYG environment. Equation Editor was developed by Design Science and is included in allMicrosoft Office versions and several other commercial applications. It is a simplified version ofDesign Science MathType . It can be used as a standalone program or it can also be used from within applications that support OLE as an embedded object. Its feature set has not changed significantly since its introduction in Word for Windows, version 2.0.For

Microsoft Office 2007 , Equation Editor is included as is, however some Office 2007 applications also include a reengineered equation editor with support for aTeX -like linear input/edit language called "Office Math Markup Language" (Office MathML orOMML ) in addition to its WYSIWYG interface. [*[*] The revised equation editor is built into the document-editing part of the interface rather than being operated through a separate dialog and being treated as an OLE object in the document. Unicode Plain Text Encoding of Mathematics is also supported. [*http://blogs.msdn.com/murrays/archive/2006/09/13/752206.aspx High-quality editing and display of mathematical text in Office 2007*]*[*] "Office Math Markup Language (OMML)" is a mathematical markup language embedded in WordProcessingML, with intrinsic support for including word processing markup like revision markings, footnotes, comments, images and elaborate formatting and styles. Equation number management is also possible using*http://www.unicode.org/notes/tn28/UTN28-PlainTextMath.pdf Unicode Nearly Plain-Text Encoding of Mathematics: Murray Sargent - Microsoft Corporation*]macro s.**Format compatibility**The OMML format is different from the World Wide Web Consortium (

W3C )MathML recommendation. Academic publishers have noted that the rendering of equations as graphics in`.DOCX`files impairs its usability for scholarly publishing as the conversion to and from MathML to OMML while converting between`DOC`and`DOCX`is not seamless and automatic. [*[*] Especially, when saving*http://www.inera.com/word2007docx.shtml Word 2007 DOCX File Format*]`DOC`files using Word 2007, equations are rendered as graphics as the older`DOC`format as well as older versions of Office do not support OMML, which prevents editing and flexibly printing the equations. [*[*] OMML is partially compatible with MathML through relatively simple*http://www.zdnet.com.au/news/software/soa/Microsoft-Office-dumped-by-Science-and-Nature/0,130061733,339278690,00.htm Microsoft Office dumped by Science and Nature*]XSL Transformations . Word 2007 has support for converting equations to/from MathML via the clipboard. [*[*] [*http://dpcarlisle.blogspot.com/2007/04/xhtml-and-mathml-from-office-20007.html XHTML and MathML from Office 2007*]*[*] Copied equations are in (Presentation)*http://www.inera.com/word2007math.shtml Word 2007 Math*]MathML format, so they can be pasted into other programs that understand this XML markup, such asMathematica . Conversely, MathML can also be pasted into a Word document and it will be recognized as an equation and displayed properly (as long as it does not contain MathML symbolic character entities such as &PlusMInus; — use numeric entities instead). The transformations that allow copying/pasting equations viaMathML are driven by two XSL stylesheets (omml2mml.xsl and mml2omml.xsl). These scripts can be used outside of Word by reading or manipulating`DOCX`XML files directly.Microsoft

Office 2008 for Mac does not currently support OMML.
