[NTG-context] embeddedxtable

With the construct \startembeddedxtable\xmlflush{#1}\stopembeddedxtable placed inside a \midaligned I used to get a neatly centered content. But now the material is shifted to the right, even sticking out of the page. Has something changed in the embeddedxtable alignment handling since the end of 2013? (The embeddedxtable macro was needed because the typeset material exists inside \startbuffer..\stopbuffer.) Hans van der Meer
