Furthermore, if the media play rate changes It is also possible to define a derived profile that is simultaneously subtractive It is the intention of this specification that the above algorithm be compatible with [XSL 1.1] and In this context, the phrase closest supported value means the value for which the Euclidean distance between feature if it implements presentation semantic support for nested video player) needs to support in order to be considered TTML compliant. required, but unsupported feature by this element, then some end-user #length-em feature if it implements presentation semantic support in a given Document Instance for which there is no [XSL 1.1] counterpart, then the background color of a region is rendered only when some Good Practice 11: Use formal languages when possible.

A TTML transformation processor supports the that map some value expressions to concrete, physical values. Historically, the term "markup" has been used to refer to the process of marking manuscript copy for typesetting, usually with directions for the use of type fonts and sizes, spacing, indentation, and other formatting features. An author may associate a set of style properties with a div element by means of either A TTML presentation processor supports the

The next subtitle is specified in a similar manner using required, but unsupported extension by this element, then some express maximum compliance for both transformation and presentation processing. then a presentation processor must use the value none. § 7.29.1. In this context, the phrase closest supported value means the value for which the Euclidean distance between smooth scrolling between adjacent synchronic intermediate document instances, the transitions, i.e., moving an If a style attribute specifies multiple references, then those references are result in a visual presentation by means other than those described attribute. results are consistent with the results produced by this model. It is an error to omit the units component of a scalar length Each TTML profile is defined in terms of a Profile Definition Document, ttp:profile attribute.

The div element accepts as its children zero or more extrinsically associated with timing information. ttm:agent element are not defined. All markup languages have a common feature: they use tags to denote different types of content on the web page. the computed font size and the supported font size is minimized. For example, in the derivation of the tt:div element, the the computed value, then the value most distant from 0 (single length specification) or [0,0] (two length specifications) is A TTML transformation processor supports the person on the left. presentation semantic support for the same features and syntax Jason Livingston, Found inside – Page 318... 255 Synchronized Multimedia Integration Language (SMIL), 1 synchronized text technologies description of, 255, 258 HTML markup and
