Most types in ASN.1 has specific tag for them. ``Obj.tag_default`` is
the default tag used during coding process. You can override it with
-either ``IMPLICIT`` (using ``impl`` keyword argument), or
-``EXPLICIT`` one (using ``expl`` keyword argument). Both arguments take
-raw binary string, containing that tag. You can **not** set implicit and
-explicit tags simultaneously.
+either ``IMPLICIT`` (using either ``impl`` keyword argument or ``impl``
+class attribute), or ``EXPLICIT`` one (using either ``expl`` keyword

There are :py:func:`pyderasn.tag_ctxp` and :py:func:`pyderasn.tag_ctxc`
functions, allowing you to easily create ``CONTEXT``
