Syntax error messages cannot be silenced for load_html/3.

Reproducible example:

?- [library(sgml)].
?- [library(http/http_open)].
?- IRI = 'https://lists.w3.org/Archives/Public/w3c-rdfcore-wg'.
?- load_html($IRI, _, [syntax_errors(quiet)]).
SGML: Redefined entity "lt"
SGML: Redefined entity "gt"
SGML: Redefined entity "amp"
SGML: Redefined entity "apos"
SGML: Redefined entity "quot"

It comes from loading the HTML DTD in an XML context, not from the document itself. Not sure what to think about this. xhtml is dead anyway ...

I ran into the exact same issue on other sites and would greatly appreciate if this warning were also silenced. For example, I need HTML parsing in cronjobs, and currently I must use:

swipl parse_html.pl &> /dev/null

to suppress such output.

The severe drawback: This also suppresses other output that is far more important, such as if the swipl executable is not found.
