The <mask> element defines an alpha mask for compositing the current object into the background. A mask is used/referenced using the {{SVGAttr("mask")}} property.

+ +
+ + +
<svg viewBox="-10 -10 120 120">
+  <mask id="myMask">
+    <!-- Everything under a white pixel will be visible -->
+    <rect x="0" y="0" width="100" height="100" fill="white" />
+
+    <!-- Everything under a black pixel will be invisible -->
+    <path d="M10,35 A20,20,0,0,1,50,35 A20,20,0,0,1,90,35 Q90,65,50,95 Q10,65,10,35 Z" fill="black" />
+  </mask>
+
+  <polygon points="-10,110 110,110 110,-10" fill="orange" />
+
+  <!-- with this mask applied, we "punch" a heart shape hole into the circle -->
+  <circle cx="50" cy="50" r="50" mask="url(#myMask)" />
+</svg>
