If you have a custom tag like:

<test /> I can add this element to the customs.json file and I see no error this is fine.

When I have <test my-attr="2" /> I can add my-attr to the custom.json file too and everything is fine.

Often you have a lot of custom tags and attr and sometimes to identify your custom things, you have a prefix my myattr-color myattr-size myattr-whatever. So it would be nice to support wildcards or regex for elements and attributes inside the customs.json file that I can write:

"attributes": {
   "myattr-*: {} // or
   "myattr-.*?": {}
}

"elements": {
   "ion-.*?": {} // All ionic tags have this prefix
}
