title: extending spring form tag library attributes
body: <p>I'm using Spring's form tag library in a Spring MVC application that I am developing. The company I am working for has implemented some company-wide policies based on the definition of custom attributes for certain tags. For instance, by default (though the inclusion of a standard javascript file) all  tags have their values automatically converted to upper case. In order to disable this one would define their tag with a custom attribute in the following way:</p>
  
  <pre><code>&lt;input type="text" uppercase="false" /&gt;
  </code></pre>
  
  <p>The problem is that the addition of these custom attributes to a spring:form tag causes an error at runtime. I've pasted the error below.</p>
  
  <pre><code>org.apache.jasper.JasperException: /WEB-INF/jsp/reportCriteria.jsp(45,5) Attribute uppercase invalid for tag input according to TLD
  </code></pre>
  
  <p>My question is: is there any way to extend the TLD to allow for these attributes, or is there any other way add these custom attributes to these spring:form tags?</p>
