Links within a STEM expression?

[stuartgalt]

Is it possible to have a link within a stem expression?

[stem]
++++
lambda(u) = C(u) + d cdot <<express:geometry_schema.offset_curve_2d.basis_curve,basis curve at location u>> (t)
++++

We tried an inline version:

stem:[lambda(u) = C(u) + d cdot] <<express:geometry_schema.offset_curve_2d.basis_curve,basis curve at location u>> stem:[(t)]

that looked mostly okay but breaks it into two bits of math.

It does not, but actually you should not want this for many reasons (the MathML won't be self-contained, the ISO editor will complain, the link won't be rendered in print, etc).

The correct way of referencing this is to use a "key" (which renders as "Where:") with a definition list, and in the definition list description you can link to the target.

Something like this is compatible with ISO DP 2:

[stem]
++++
X = y^z
++++

[%key]
stem:[X]:: is the big X;

stem:[y]:: is the small y (see <<my-anchor>>);

stem:[z]:: is something else.

I believe the "pseudocode" block in Metanorma does support cross-referencing but again it is not to be used in this manner.

Thank you. We will use the %key and put the links there.
