title: Is it possible to split a string across multiple lines in an XML file? If so, how?
body: <p>I've got an XML config file with some really long strings.  Generally, I format my source files, etc. so that they can be read without scrolling.  I'd like to do the same to this config file.</p>
  
  <p>Is there a way to split the string across more than one line?  Hopefully, what I'm asking for is obvious but a picture says a thousand words so, e.g. value, below.</p>
  
  <pre><code>&lt;add name="validation"
       type="Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF.ValidationElement, Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /&gt;
  </code></pre>
  
  <p>If I break the above string to look like this:</p>
  
  <pre><code>&lt;add name="validation"
       type="Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF.ValidationElement,
       Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /&gt;
  </code></pre>
  
  <p>my apps fails with: </p>
  
  <p>"An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'validation' cannot be added to this element.  Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions.
  Parameter name: element "</p>
  
  <p>It seems that it's sensitive to line-breaks in the string.</p>
