It's not HTML u dummies it's XML
I don't think so. Not at all. XML is case sensitive, HTML isn't.
If it was XML it should make a difference if you'd write...
<p>...</p>
...or...
<P>...</P>
In OFP briefings and overviews this makes no difference at all.
From an official BIS briefing.html (not briefing.xml or briefing.xsl) file:
<html>
<head>
<meta http-equiv="Content-Type"
content="text/html; charset=windows-1250">
<meta name="GENERATOR" content="Microsoft FrontPage Express 2.0">
<title>Titulek</title>
</head>
...
Any doubt about what type of document that is? I do not think so.
Also, the initialization of an XML file would look something quiet like this...
<?xml version="1.0" standalone="yes/no" encoding="UTF-8"?>
...or at least...
<?xml version="1.0" encoding="iso-8859-1"?>
...wouldn't it? I never saw an OFP briefing or overview file that had something like that in it. To be honest, I dunno sh*t about XML files, but... anyway.
