\type ,\meaning eror check

["luigi.scarso" <luigi.scarso@logosrl.it>]

I have this problem:

%% test.tex
%-save this with utf-8 encoding--------------
\language[it]
\enableregime[utf]
\newif\ifArticleError
%%
\def\startArticle[#1]{%
\getparameters[ARTICLE][#1]
\setbox101=\vbox{%
\csname ARTICLEdescription\endcsname%
}
%% here some sorts of checking
%% if there are some errors
%% while expanding
%% \csname ARTICLEdescription\endcsname ;
%% check will change state of \ifArticleError
%%
\ifArticleError
%%  errors:
%% typescript macros \ARTICLEdescription
\type{description:}%
\edef\T{\expandafter%
\meaning\csname ARTICLEdescription\endcsname}%
\aftersplitstring \T \at>\to\Temp%
\expandafter\type\expandafter{\Temp}%
\else %% else ok
\type{OK}%
\fi
}
%%
\starttext
{{\bf Hòàà}\framed{wrong  framed macros}}
\startArticle[description={{\bf Hoòaà}\framed{ok  framed macro}}]
\startArticle[description={{\bf Hoòaà}\Framed{WRONG  framed macro}}]
\stoptext
%--------------------------------------------------------------------

where
oò := {o\`o}
aà := {a\`a}

compile it with
$>texexec --pdf --batch test.tex

Problems

   1. i dont't know how to make checking
   2. \type does not combine well with \meaning: ò (ie {\`o} ) is not show.

thanks in advance
