OpenSAML user discussion

Couple of items.  First you get an XSString builder as follows:

buildFactory.getBuilder(XSString.TYPE_NAME);

Then you set the value using the XSString.setValue() method.  So your 
code should look like this:

XMLObjectBuilder<XSString> builder = 
buildFactory.getBuilder(XSString.TYPE_NAME);

XSString attributeValue = 
builder.buildObject(AttributeValue.DEFAULT_ELEMENT_NAME, 
XSString.TYPE_NAME);

attributeValue.setValue("My Attribute Value");
