Hi -
I barely ever see equations with titles and have never used one myself,
so I cannot speak for aspects concerning titles. That said, all this
looks perfectly reasonable to me, and would well serve the use cases in
my field, in particular,
> 1. equation elements are numbered, and informalequation elements are not.
These will be easily customizable like any other xrefs, as described in
Ch. 15 of the Complete Guide, I take it:
> 6. An xref's generated text for a cross reference to an equation with
> title looks like this by default:
>
> Equation 3.2, "My equation title"
>
> 7. An xref's text for an equation without title looks like:
>
> Equation 3.2
