+ = Segmentation Hints =
+ 
+ [R025] Methods, independent of the semantic, of the elements must exist to provide hints on how to break down document content into meaningful runs of text.
+ 
+ Many applications that process content for linguistic-related tasks need to be able to perform a basic segmentation. They need to be able to do this without knowing about the semantic of the elements. The elements marking up the document content should provide generic clues to help such process.
+ 
+ In this requirement a 'text run' is defined as the longest collection of sequentially traversable nodes that, if you remove the tags, has a continuous linguistic meaning. (for example a paragraph with two consecutive sentences is a single text run, but two sentences with one embedded in the other constitute two text runs.) '''[YS- Not sure about this definition]'''
+ 
+ From this viewpoint, one can distinguish several types of element:
+ 
+  * Type 1: Elements that do not contain direct text nodes. For example: <table> in XHTML.
+ 
+  * Type 2: Element that contain mixed nodes belonging to one or more text runs. For example: <p> in XHTML.
+ 
+  * Type 3: Elements that contain mixed nodes belonging to a single text run. For example: <img> in XHTML 2, or <image> in DITA. (Note: <img> XHTML 2 is different from <img> of XHTML 1.1).
+ 
+  * Type 4: Elements that contain mixed nodes belonging to an element of type 2 or 3. For example: <strong> or <span> in XHTML.
+ 
+  * '''[And possibly]''' Type 5: Empty elements belonging to an element of type 2, 3, or 4 and indicating a strong possibility of sub-segmentation. For example: <br/> in XHTML. '''[But I'm not sure this belong to ITS, because: a) it affects sub-segmentation not the text runs, b) such elements would probably be considered bad practice).]'''
+ 
+ A processor should be able to know from a method or infer from the content to which category or categories each element belongs.

+ '''[YS- Previous text is below just in case we need it back]'''
