Dear all,
The combination of tagging and \startalign and \text leads to a compilation
error.
Minimal example:
\setupbackend[format=pdf/ua-2]
\setuptagging
[state=start,
preset=basic,
level=2,
option=interaction,
]
\starttext
\startformula
\startalign
\NC X^{\text{tan}} \NC = 0\NR
\stopalign
\stopformula
\stoptext
results in the attached error log.
Commenting out the preamble or removing the alignment ot removing the
\text{tan} compiles fine.
Any workaround/fix will be much appreciated.
Thanks, as always.
Matthias
