Sorry to have overlooked this. In my opinion:
> <lem>standard reading<add hand="#h1" place="above"><metamark
> <rdg hand="#h1" rend="margin">alternate reading<metamark
> function="variant" rend="ṭa"/></rdg>
> What I am especially unsure about is:
> * The position of the metamark entries as children of the lem/rdg.
I think it is well marked up as a child of <add>
> * The @rend on rdg (abusing @rend here for @place).
Mmmh I’d prefer to have an <add place=””> within the <rdg> which will also match the fact that the <metamark> is within an <add>
