[NTG-context] parsing issue with \math{} inside natural table

Hi, I ran into a case where a natural table has an issue when it contains inline math and an alignment character is used. Here's a small example which triggers the problem: \starttext< \bTABLE< \bTABLEbody< \bTR< \bTD[alignmentcharacter={.},aligncharacter=yes]{\le 4.0\math{-}}\eTD< \eTR< \eTABLEbody< \eTABLE< \stoptext< However, if I replace \math{-} with $-$, the file works. Am I correct that $-$ and \math{-} should be interchangeable? Thanks, Brian
