I have trouble with the xexpr conversion of a script.  
I run a very simple case extracted from a much larger program:

```scheme
#lang web-server
    (require xml net/url)
(xexpr->string '(script "SetTimeOut(() => {let d = new Date();" ))

```

The result, run in drracket:

```scheme
"<script>SetTimeOut(() =&gt; {let d = new Date();</script>"

```

That \> should still be a greater-than sign. It is no longer correct javascript.  
A bug? Or am I doing it wrong?

You can use [`html-unescaped-tags`](https://docs.racket-lang.org/xml/index.html#%28def._%28%28lib._xml%2Fmain..rkt%29._html-unescaped-tags%29%29) to prevent the incorrect transformation.

The parameter `current-unescaped-tags` holds tags that needs unescaped contents.  
You need to set to `html-unescaped-tags`. If I recall correctly this was done  
to have backward compatibility with older code.

```scheme
(parameterize ([current-unescaped-tags html-unescaped-tags])
  (xexpr->string '(script "SetTimeOut(() => {let d = new Date();" )))

```

If you already happen to be using the `txexpr` package (or don't mind an extra dependency) it also includes a function [`xexpr->html`](https://docs.racket-lang.org/txexpr/index.html#%28def._%28%28lib._txexpr%2Fmain..rkt%29._xexpr-~3ehtml%29%29) that skips the content of `<script>` or `<style>` blocks.
