<para>Sets direction of text flow and text alignment based on locale.
The value is normally taken from the gentext file for the 
lang attribute of the document's root element, using the 
key name 'writing-mode' to look it up in the gentext file.
But this param can also be
set on the command line to override that gentext value.
