Not that any user agent pays attention to it, but the <math> element does have the "overflow" attribute. From the spec: ============== In cases where size negotiation is not possible or fails (for example in the case of an extremely long equation), this attribute is provided to suggest an alternative processing method to the renderer. Allowed values are scroll The window provides a viewport into the larger complete display of the mathematical expression. Horizontal or vertical scrollbars are added to the window as necessary to allow the viewport to be moved to a different position. elide The display is abbreviated by removing enough of it so that the remainder fits into the window. For example, a large polynomial might have the first and last terms displayed with "+ ... +" between them. Advanced renderers may provide a facility to zoom in on elided areas. truncate The display is abbreviated by simply truncating it at the right and bottom borders. It is recommended that some indication of truncation is made to the viewer. scale The fonts used to display the mathematical expression are chosen so that the full expression fits in the window. Note that this only happens if the expression is too large. In the case of a window larger than necessary, the expression is shown at its normal size within the larger window. ============== This doesn't specifically say "don't linewrap", but it is close. It does seem like it should be taken into account by any mechanism that gets developed, although I don't see developing a mechanism as a burning need. I think it is more important to encourage auto linebreaking in renderers.

While the CSS nowrap directive is probably a reasonable solution in Web contexts, it seems like there should be a way of disabling line breaking in MathML in non-CSS environments. --Robert Robert Miner Director, New Product Development Design Science, Inc. 140 Pine Avenue, 4th Floor Long Beach, California 90802 USA Tel: (651) 223-2883 Fax: (651) 292-0014 robertm@dessci.com www.dessci.com ~ Makers of MathType, MathFlow, MathPlayer, WebEQ, Equation Editor, TexAide ~ > -----Original Message----- > From: www-math-request@w3.org [mailto:www-math-request@w3.org] On Behalf > Of William F Hammond > Sent: Wednesday, June 06, 2007 12:17 PM > To: www-math@w3.org > Subject: Re: linebreaking mathml > > > Hi Bruce, > > You write on an issue concerning presentation MathML in web browsers: > > > I suppose that when MathML was originally developed, the authors > > imagined that the browser would be responsible for line breaking. > > ... > > I am concerned with the community of authors having TeX backgrounds. > As one such author I want complete control over linebreaks in math. > I believe this is the general attitude among TeX users for traditional > print. > > I want to emulate that as much as possible in XHTML+MathML. > > Accordingly for all <math> elements I set the "white-space" CSS > property to "nowrap".
