Hi,

When using the Xalan serializer bundled with Xerces 2.9.1 I get a
fatal error whenever an attribute value contains '<' (left angle
bracket):

> The value of attribute "bar" associated with an element type "foo"
> must not contain the '<' character.

I believe this is a bug since if I instead use the now deprecated
native serializer of Xerces, I don't get the error. Also, the the "DOM
Level 3 Core" specification under "setAttributeNS" says this:

> So any markup (such as syntax to be recognized as an entity
> reference) is treated as literal text, and needs to be appropriately
> escaped by the implementation when it is written out.


Here is my code:

> DOMImplementationRegistry registry = DOMImplementationRegistry.newInstance();
>
> DOMImplementation core = 
> (DOMImplementation)registry.getDOMImplementation("Core 3.0");
> Document document = core.createDocument(null, "foo", null);
> document.getDocumentElement().setAttributeNS(null, "bar", "<");
>
> DOMImplementationLS ls = 
> (DOMImplementationLS)registry.getDOMImplementation("LS 3.0");
> LSSerializer serializer = ls.createLSSerializer();
> serializer.getDomConfig().setParameter("error-handler", new DOMErrorHandler()
> {
>   public boolean handleError(DOMError e)
>   {
>     System.err.println("Error: "+e.getMessage());
>     return false;
>   }
> });
> serializer.writeToString(document);


Please let me know if this is required behaviour rather than a bug.
