title: Custom attrs parameter used in styles.xml
body: <p>I have a set of custom Android layout parameters defined in attrs.xml. Now I would like to use some tags in my styles.xml file.</p>
  
  <p>At the moment I get this error:</p>
  
  <pre><code>error: Error: No resource found that matches the given name: attr 'custom:tag'
  </code></pre>
  
  <p>I have tried declaring custom XML namespace as follows:</p>
  
  <pre><code>&lt;resources
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:custom="http://schemas.android.com/apk/res/com.my.project"
  &gt;
  </code></pre>
  
  <p>hoping, that the same logic used in every layout declaration can be applied here, but with no success.</p>
