title: Building TestLink
body: <p>I downloaded yesterday TestLink source code and I try to buil it in eclipse. I resolved most errors which I had, but still I have one, which is really nervous:</p>
  
  <pre><code>A '(' character or an element type is required in the declaration of element type "f".
  </code></pre>
  
  <p>This error shows in two dtd files. Here is code from one of them:</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;!ELEMENT schema (table*, sql*)&gt;
  &lt;!ATTLIST schema version CDATA #REQUIRED&gt;
  &lt;!ELEMENT table ((field+|DROP), CONSTRAINT*, descr?, index*, data*)&gt;
  &lt;!ELEMENT field ((NOTNULL|KEY|PRIMARY)?, (AUTO|AUTOINCREMENT)?, (DEFAULT|DEFDATE|DEFTIMESTAMP)?, 
  NOQUOTE?, CONSTRAINT*, descr?)&gt;
  &lt;!ELEMENT data (row+)&gt;
  &lt;!ELEMENT row (f+)&gt;
  &lt;!ELEMENT f (#CDATA)&gt;
  &lt;!ELEMENT descr (#CDATA)&gt;

  &lt;!ATTLIST sql name CDATA #IMPLIED platform CDATA #IMPLIED, key CDATA, prefixmethod (AUTO|MANUAL|NONE) &gt;
  </code></pre>
  
  <p>The problem is with this line:</p>
  
  <pre><code>&lt;!ELEMENT f (#CDATA)&gt;
  </code></pre>
  
  <p>And can't find anything similar on google. Thanks in advance for any suggestion.</p>
