I want to add the following attributes to all svg element in the page:

aria-hidden="true" focusable="false" role="img" xmlns="http://www.w3.org/2000/svg"

1. If adding them manually, it will bloat the whole page and is time-consuming.
2. If using JavaScript, it will delay the page loading speed.
3. It seems that CSS also cannot do this task, see I want to change attribute value of a class using CSS

Are there any other choices?
