illegal characters in xml...

flickr.interestingness.getList (and other services,
presumably) may
return illegal characters in the xml.  namely, the xml
attribute title
has a value that includes 10 decimal, aka LineFeed (see
below for an
example).

I can't quite parse the authorities on what characters are,
strictly
speaking, illegal in the xml spec.

see: http://www.
w3.org/TR/REC-xml/#NT-AttValue
defines it as [^<&"] ie. everything except
double-quotes, ampersands
and less-than this would appear to suggest that linefeeds
are legal in
attribute values.

Is this a bug or not?

thanks,
charles.
