RE HTML: If you don't require the file to start with the DOCTYPE 
declaration, then it could start with <head>, <title>, or any of the HEAD 
elements, as the <html> and <head> start and end tags are optional.  It could 
also start with a comment declaration (<!-- ... -->).  For legacy HTML 
probably the only safe statement is that the first non-whitespace character 
ought to be a '<'.

OTOH the DOCTYPE isn't really optional.

For XHTML things are simpler -- there are no optional start tags, and you can 
only start with the (optional) <?xml or the (mandatory) DOCTYPE declaration.
