For example:
.... blah blah <add resp=V1.1 rend=sidebar> Not. </add> blah blah
or similarly
.... blah blah <del resp=V1.1 rend=sidebar> Not. </del> blah blah
This may look like a slightly strange use for these tags, which were
designed for use when transcribing from manuscripts, but I think
legitimate. Problems arise if the thing you want to add or delete spans
other elements. The following, for example, is ILLEGAL
<p> this para starts out well but
<del resp=V1.2> from here on into the next
<p> paragraph is a load of nonsense which is why it's been
deleted and </del> ends suddenly.
The easiest (of several) methods suggested by the TEI for dealing with
this is to use the <addspan> element thusly:
<p> this para starts out well but
<delspan resp=V1.2 to=XY123> from here on into the next
<p> paragraph is a load of nonsense which is why it's been
deleted and <anchor id=XY123> ends suddenly.
Note the use of the TEI <anchor> element -- no relation to anything
HTMLers know under a similar name -- to mark a point in the document,
solely so that it can have an identifier attached to it, so that some
other element (the <delspan>) can point to it.
