Missing documentation on how to expand HTML validation

[Rhobal]

After activating the eclipse plugin, I'm getting a ton of validation warnings for directives of angular extensions, such as uib-tooltip or translate (from angular translate, not the HTML5 attribute)

I'm loading all libraries from cdnjs.cloudflare.com, and the Subresource Integrity attributes on the script tags (integrity and crossorigin) also produce validation warnings

Can you please document how I could add attributes to the validation to get rid of the warnings?

[Rhobal]

I could remove many warnings by prefixing attributes with data- but that doesn't work for element directives. Would still appreciate support on how to accept the attributes in validation

@Rhobal I'm very busy with Angular2 Eclipse, no time to do this issue -(
