Is there a custom element, which allow the use of RFC6570 URI templates? This is very similar to this question. Here's the sample HTML used there.
<form action="/orders/{id}" method="get">
<input type="text" name="id"/>
<input type="submit" value="Submit"/>
</form>
I'm asking specifically about a Web Component though, so something like either
<form is="templated-form">
or
<templated-form>
