Firefox support of external parameter entities

Hi All,

Code sequence shown at bottom raises error when file is opened directly by
Firefox 0.8. Error is:

XML Parsing Error: undefined entity
Location: file:///C:/firefox_GUI/test_firefox.xml
Line Number 13, Column 19:
<TITLEBAR_TITLE>&producttitle;</TITLEBAR_TITLE>
------------------^

File 'test.globals' contains the entity definition for &producttitle; I am
thinking that test.globals was not processed by Firefox.

Does Firefox support properl instantiation/parsing of an external parameter
entity reference?

TIA.


<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="gui.xsl"?>

<!DOCTYPE GUI SYSTEM "mydoc.dtd" [
<!ENTITY % globals SYSTEM "test.globals">
%globals;

]>

<GUI>

<TITLEBAR>
<TITLEBAR_TITLE>&producttitle;</TITLEBAR_TITLE>
</TITLEBAR>

</GUI>

Thanks.
