Hi,I'm trying to declare a new font style. I declare it with \definefontstyle [sx] [sx] but the compilation fails when I use \sx in my document.I found an older message from 2009 similar to my issue but with public solution. May be some private response from Hans Hagen is missing? (https://mailman.ntg.nl/pipermail/ntg-context/2009/ )043067.html Here is a minimal example:\definefontstyle [sx] [sx]\definetypeface [source] [sx] [semiextended] [myriadpro] [optical]\starttypescript [semiextended] [optical] [size]\definebodyfont [11pt] [sx] [tf=SansSemiExtended sa 1]\stoptypescript\starttypescript [semiextended] [myriadpro]\definefontsynonym [SansSemiExtended] [file:MyriadPro-SemiExt.otf] [features=default]\stoptypescript\starttext{\sx ABCDEFGHIJKLM\parNOPQRSTUVWXYZ\parabcdefghijklm\parnopqrstuvwxyz\par1234567890}\stoptextThanks for your help,Antoine C.
