Matthias,
this should work:
\enabledirectives [backend.usetags=crap]
\setuptagging[state=start]
\setupstructure[state=start]
\setupbackend
[format=PDF/A-3a,
intent=sRGB IEC61966-2.1,
level=0]
\setupbackend[format=pdf/ua-1]
\setupexternalfigures[location=default]
\starttext
\externalfigure[cow][label={this is a cow}]
\stoptext
Let us know whether your Acrobat reads the text (but this is validated
fine by veraPDF).
I hope it helps,
Pablo
