### Describe the feature you'd like to request I would like to be able to create a link that, when clicked, opens in a new tab. I found that [in the documentation](https://myst-parser.readthedocs.io/en/latest/syntax/optional.html#syntax-attributes), "only certain key-value attributes are supported for each syntax". ### Describe the solution you'd like I would like `[here](example.md){target="_blank" rel="noreferer noopener"}` to work. ### Describe alternatives you've considered My workaround is to directly use `<a href="example.html" target="_blank" rel="noreferer noopener">`
