Hi,

I'm looking for some simple XML/HTML escape functions amongst Virtuoso's 
built-in functions, but I can't find anything other than http_value (http_url 
etc.) which are awkward to use for a string result (via string_output_string).

Ideally I was expecting to find something similar to the PHP urlencode and 
htmlspecialchars functions that simply return the escaped string. Am I just 
missing something?

I basically just wanted this to fix /rdfdesc/description.vsp to produce valid 
XHTML but it uses sprintf substitutions where some variables need to be escaped 
first (_url, _label in rdfdesc_http_print_r). I noticed some other syntax 
breakage in there also (closing " on iframe height attribute, missing alt on 
img 
tags.. use of iframe itself even) so I was intending to make a patch.

Thanks,
-Will
