[oXygen-user] Important tip when using Oxygen XML

[Oxygen XML Editor Support (Radu Coravu)]

Hi, Roger, Joel,

One more thing in addition to this, the xml:space attribute does not 
need to be specified directly in the XML, it can be defined as an 
attribute with a default value in the associated schema/DTD.

For example a codeblock defined in the DITA DTD:

> <!ENTITY % codeblock.attributes
>               "%display-atts;
>                spectitle
>                           CDATA
>                                     #IMPLIED
>                xml:space
>                           (preserve)
>                                     #FIXED
>                                     'preserve'
