toString() method.

Reporter: lifecoder | Owner: scala-xml_team
Type: defect | Status: new
Priority: normal | Component: XML support
Keywords: |
----------------------+-----------------------------------------------------
It looks inconsistent when values inside the xml elements are implicitly
converted to string but values in the xml attributes are not.

Reproducing:
{{{
scala> {2+2}

res2: scala.xml.Elem = 4

scala>

:5: error: overloaded method constructor UnprefixedAttribute
with alternatives
(String,Option[Seq[scala.xml.Node]],scala.xml.MetaData)scala.xml.UnprefixedAttribute

(String,String,scala.xml.MetaData)scala.xml.UnprefixedAttribute

(String,Seq[scala.xml.Node],scala.xml.MetaData)scala.xml.UnprefixedAttribute
cannot be applied to (java.lang.String,Int,scala.xml.MetaData)
