How do you make a block comment in SVG

Question

I'm trying to learn SVG for the first time but the code seems to have an issue with my block comments. I'm using:

/* This is my
 * block comment
 */

And when I run my code, I get the following error:

'return' statement outside of function
line: 116, column: 4

That so happens to be immediately before my block comment.

As SVG is XML, you can use XML style comments:

<!-- 
    comment 
-->

For example:

<g onclick = "setScale(1)">
    <rect id = "scale1" x = "120" y = "10" width = "30" height = "30"
        fill = "#ffc" stroke = "black"/>
    <!-- 
        this text describes middle rectangle
    -->
    <text x = "135" y = "30" text-anchor = "middle">M</text>
</g>

Or you can exclude some part of code:

<!--
     this group is disabled for testing    
<g onclick = "setScale(1)">
    <rect id = "scale1" x = "120" y = "10" width = "30" height = "30"
        fill = "#ffc" stroke = "black"/>
    <text x = "135" y = "30" text-anchor = "middle">M</text>
</g>
