body: <p>I use symbol tag with id in my sag file as it is described in the following link:
  <a href="http://css-tricks.com/svg-symbol-good-choice-icons/" rel="nofollow">http://css-tricks.com/svg-symbol-good-choice-icons/</a></p>
  
  <p>After magnification with grunt task svgmin, all of my ids are removed from my svg file.</p>
  
  <p>My grunt task is as follows:</p>
  
  <pre><code>svgmin: {
      options: {
        plugins: [
          { removeViewBox: false},
          { removeUselessStrokeAndFill: false}, 
          { removeEmptyAttrs: false }
        ]
      },
  
    dist: {
      files: [{
        expand: true,
        cwd: '&lt;%= yeoman.app %&gt;/images',
        src: '{,*/}*.svg',
        dest: '&lt;%= yeoman.dist %&gt;/images'
      }]
    }
  },
  </code></pre>
  
  <p>Is there any work around for this problem?</p>
