=Cue Text=
WebVTT chapter title text is syntactically a subset of WebVTT cue text, and WebVTT cue text is syntactically a subset of WebVTT metadata text. Conformance checkers, when validating WebVTT files, may offer to restrict all cues to only having WebVTT chapter title text or WebVTT cue text as their cue payload; WebVTT metadata text cues are only useful for scripted applications (using the metadata [http://www.whatwg.org/specs/web-apps/current-work/#text -track -kindtext track kind]).
A WebVTT file whose cues all have a cue payload that is WebVTT chapter title text is said to be a WebVTT file using chapter title text.
=Test List=
==Base/Metadata tests==
* No cue text
* No cue text with line feed character(s)
* No cue text with carriage return character(s)
* No cue text with a combination of line feed and carriage return character(s)
* Simple one-line of cue text - no other components
* multiple-line text
** line terminator in between
==Chapter Title Text==
* Cue text consisting of only an ampersand escape character
* Cue text consisting of only a less than escape character
* Cue text consisting of only a greater than escape character
* Cue text consisting of only a left-to-right escape character
* Cue text consisting of only a right-to-left escape character
* Cue text consisting of only an nbsp escape character
* Cue text different combinations (vary tests for different components: multiple ampersands, all types of components, etc.)
** 2+ components that are separated from each other with line terminators
* Cue text including escape character(s)
** Line terminators
==Cue Text==
Note that these may overlap with group 6 - text tags, we'll probably only need to cover the first 2.
We'll cover these for sure:
* Cue text that uses a span tag
* Cue text that uses 2+ span tags
** Separated with line terminator
These should automatically be covered by the text tags testing as they create tests for each tag:
* Cue text that uses a class span tag
* Cue text that uses an italics span tag
* Cue text that uses a bold span tag
* Cue text that uses an underline span tag
* Cue text that uses a ruby span tag
* Cue text that uses a voice span tag
* Cue text that uses a timestamp tag
