properties - Can I separate tags with comma in HTL Slightly?

Question

My problem is: I have to customize properties of a meta tag on AEM Console.

I have this meta tag:

<meta name="tags" data-sly-test="${properties.tag}" content="${properties.tag}" />

If an utent add more attributes on AEM console, I need that these attributes are separeted by ';'.

The output should be:

<meta name="tags" content="hello;world;laptop;screen"/>

You can use the join option (https://github.com/adobe/htl-spec/blob/master/SPECIFICATION.md#124-array-join):

content="${properties.tag @ join=';'}"
