  It must be possible to specify for a given element content how white spaces are to be handled (i.e. whether they are to preserve or collapsible).

- Knowing whether the white spaces in a given element are collapsible or not is important for proper segmentation and matching when using computer assisted translation tools.

- The xml:space="preserve" attribute provides most likely a good solution for this requirement at the document instance level.

- The whiteSpace constraint defined in the [http://www.w3.org/TR/xmlschema-2/#rf-whiteSpace XML Schema Part 2: Datatypes Second Edition] may be a good solution for this requirement at the schema level.

+  * It is important for translation tools to make a difference between the first example (text can be collapsed safely) and the last two (text should not be collapsed).
+ 
+  * It is important for translation tools to have a way to address the differences between the two last examples (i.e. how line-breaks should be treated).
+ 
+  * The indication of whether white-spaces should be preserved or not should be accessible from the document itself, as defining the information at the rendering level (e.g. in a CSS style-sheet) may not be accessible for the translation tool.

- === Notes ===
+ == Notes ==
  
  There are case where the white space handling can be overriden at the style sheet level only, bypassing information withing the XML document itself: CSS allows the property 'white-space' (See [http://www.w3.org/TR/REC-CSS2/text.html#white-space-prop]).
