Specification of SVG header with DOCTYPE TRANSITIONAL

I have a bunch of old SVG standalone files which used to work in
various browsers. Using the validator I get messages relating to the
mismatch between attributes which are only recognized with
TRANSITIONAL DOCTYPE. However there is no clear indication of how to
specify the TRANSITIONAL (loose) DOCTYPE when specifying an SVG
document.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<!-- <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
  "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> -->

<!-- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd"> -->

<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">

<svg xmlns="http://www.w3.org/2000/svg" version="1.1"
      width="120" height="120" viewBox="0 0 236 120">

Typical validator msg is:

Warning Mismatch between Public and System identifiers in the DOCTYPE
declaration

This document uses an inconsistent DOCTYPE declaration. The System
Identifier http://www.w3.org/TR/html4/loose.dtd declares the HTML 4.01
Transitional document type, but the associated Public Identifier
-//W3C//DTD SVG 1.1 Transitional//EN does not match this document
type.

The recommended Public Identifier for
http://www.w3.org/TR/html4/loose.dtd is -//W3C//DTD HTML 4.01
Transitional//EN.

I understand that the probable wOuld be resolved if I wanted to avoid
attributes only available in TRANSITIONAL -- namely switching to
STRICT. I am trying to avoid rewriting the SVG content
