\textbf{stringresponse} implements a string answer. An internal \textbf{textline}
tag (see \textbf{\ref{textline}}) is necessary for the student's
response to go in. It can check the string for either case or order.
Possible attributes are:

\begin{itemize}
\item \textbf{answer}\index{answer}: required. Specifies the correct answer,
either a perl list or scalar.
\item \textbf{type}\index{type}: optional. Specifies how the string is
checked (like the CAPA styles). Possible values are:

\begin{itemize}
\item \textbf{cs}\index{cs}: \textbf{c}ase \textbf{s}ensitive, order important.
\item \textbf{ci}\index{ci}: \textbf{c}ase \textbf{i}nsensitive, order
important. 
\item \textbf{mc}\index{mc}: case insensitive, order unimportant. The mnemonic
for this option is {}``\textbf{m}ultiple \textbf{c}hoice'', which
is how it was used in CAPA: To allow the user to specify choices from
a multiple choices problem, as in {}``adce'', meaning parts a, d,
c, and e are true. Order didn't matter in such a problem. In LON-CAPA,
using \textbf{optionresponse} with True and False foils would be preferable,
but this will remain supported for easier CAPA-to-LON-CAPA conversion.
