I am trying to figure out if I can use, and how to use, `elemtag` and `elemref` to create hyperlinks to equations. I would like to do something like:

`@elemtag{eqn1 @($$ "1 + 1 = 2")}`

and later be able to create a link with,

`And we can see in @elemref{eqn1 "equation 1"} that ...`

Any advice whether these commands can work for that use and a minimal example?

May be something like this

```scheme

#lang scribble/base

@elemtag{eqn1} $$ "1 + 1 = 2") @(linebreak)

and later be able to create a link with,

And we can see in @elemref["eqn1"]{equation 1}

```

Works great. Here is my specific use for reference. Thanks.

```scheme
@elemtag{eqn1}
@$$["\\frac{d^2 s}{dt^2} = -P~s"]{\tag{1}}
@(linebreak)

```

...

`How do we know the formula for acceleration? We were given it in @elemref["eqn1"]{Equation 1} above.`
