```Dear list,

I have the following sample:

\setupbodyfont[pagella]
\definefontfeature[asc]
[c2sc=yes, smcp=yes]
\starttext
\startTEXpage[offset=1em]
text
\doifelsecurrentfonthasfeature{asc}
{yes}{no}
\doifelsefontfeature{asc}
{yes}{no}
\doifunknownfontfeature{asc}
{yes}{no}\\
\feature[+][asc]
text
\doifelsecurrentfonthasfeature{asc}
{yes}{no}
\doifelsefontfeature{asc}
{yes}{no}
\doifunknownfontfeature{asc}
{yes}{no}
\stopTEXpage
\stoptext

Sorry, but which is the right way to check when the font feature is
being deployed?
