Request For Enhancement: filter on MIMEtype

[Ruud Steltenpool, http://svg.startpagina.nl]

Somewhere in or after 
http://www.gnu.org/software/wget/manual/wget.html#Types-of-Files
i'd like to find something about an option to filter based on MIMEtype.
SVG content for example often doesn't have a .svg extension, but for 
example .php .jsp .asp

Thanks,

Ruud
