The new code needs "trim()" in the above line.
Conversion to lowercase can be done once, but trimming must be done
for each encodingName in the loop there.

#rule
A construct "#" is defined, similar to "*", for defining lists of
elements. The full form is "<n>#<m>element" indicating at least
<n> and at most <m> elements, each separated by one or more commas
(",") and OPTIONAL linear white space (LWS). This makes the usual
form of lists very easy; a rule such as
( *LWS element *( *LWS "," *LWS element ))
[/quote]
Thus LWS is allowed between list elements.
