In the future there will come a point when none latin charactures will have to
be available to the user. to handle this the viewer must pass the correct ISO
entity value before processing the xml threw the xsl translator.

currently the viewer is hard coded for:

<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"/>

In the future this should be dynamic to handle the different ISO's during
translation.

In addition, to help this the xml schema may have to have a new element to hold
the ISO character standard.

Currently only decimal ascii codes are valid in the xml documents. Currently I
do not know if this will have to change, but this allows the validation of the
xml to be less complicated and dependent on many namespaces.
