How to remove id from svg?

Question

SVG

I would like to know how to remove the id and url in the mask in the SVG tag. There is no desire to rewrite a new id every time.

<svg width="15" height="15" viewBox="0 0 12 12" fill="none" xmlns="http://www.w3.org/2000/svg">
  <mask id="mask15" width="12" height="12">
    <path d="M6.40438 2.71801L5.99997 3.12974L5.59556 2.71801C4.61897 1.72376 3.0589 1.60396 2.0711 2.43624C0.853665 3.46102 0.855868 5.24725 1.88573 6.29824L5.60707 10.0896C5.71347 10.1981 5.85224 10.2569 5.99997 10.2569C6.15078 10.2569 6.28714 10.1996 6.39311 10.0915L10.1135 6.30108C11.1436 5.24788 11.147 3.46199 9.92893 2.43632C8.9404 1.60527 7.38016 1.72459 6.40438 2.71801Z" fill="none" stroke="#fff" />
   </mask>
   <g mask="url(#mask15)">
     <rect width="12" height="12" fill="white" />
   </g>
</svg>

Answer 1

1. No, it's SVG, not HTML.
2. Collect everything in one defs and reuse if possible, but then there will simply be a little less ID's.
