Description

interface SVGFEComponentTransferElement {
    appendChild(newChild: SVGFEFuncAElement): SVGFEFuncAElement;
    appendChild(newChild: SVGFEFuncBElement): SVGFEFuncBElement;
    appendChild(newChild: SVGFEFuncGElement): SVGFEFuncGElement;
    appendChild(newChild: SVGFEFuncRElement): SVGFEFuncRElement;
    appendChild(newChild: Comment): Comment;
}

interface SVGFEMergeElement {
    appendChild(newChild: SVGFEMergeNodeElement): SVGFEMergeNodeElement;
    appendChild(newChild: Comment): Comment;
}

...

to override the generic appendChild(Node) inherited from Node, and so on. This would make it an error to append a <g> to a <feMerge> for example.
