Nested assets error

And this triggers a cross-reference error:

There is a crossreference to an instance of formula nested within note:  target="eq6-8"

Today:

Syntax: (XML Line 000682): There is an instance of table nested within example
Syntax: (XML Line 000722): There is an instance of table nested within example
Syntax: (XML Line 000762): There is an instance of table nested within example

The original warning:

There is a crossreference to an instance of formula nested within note: target="eq6-8"

is no longer raised: we allow notes to contain anything, including formulas. Formula referencing is either by clause or consecutive in the document; formulas being embedded within notes, or indeed anything else, are no longer considered a problem.

The warning is now only issued for any instances of example | figure | note | termnote | termexample | table, containing example | figure | table (except for figure/figure). I consider that warning warranted: examples containing examples, and tables containing tables, are unusual enough that they should be warned about, and their numbering may be surprising. (We have not modelled subexamples or subtables like we have subfigures). It is not at all clear that tables contained within examples should be numbered at all.

As the warning log also indicates, right now Metanorma does not know how to crossreference example/table. That's current implementation: if a table is embedded within a numbered asset (example/table, figure/table, note/table), it is not assigned a label or a cross-reference by design. I used to do that with embedded figures as well.

I'm going to relax that last constraint, because I think it is overly presumptuous, as found in metanorma/metanorma-standoc#719 . If people want to embed tables and examples, they should be allowed to cross-reference them. They have already been warned about them. If they are surprised that an embedded table ends up labelled, they can use %unnumbered on the table.
