Fix for better control over XML output. Hope this little tip helps.

description

First we emit nodes, but they are all joined up

<that>x</that><that>x</that><that>x</that><that>x</that>  

Then attempt to inject CR after end of "that". But only injects CR after "x"

<that>
</that><that>x
</that><that>x
</that><that>x
</that>

Then we try to put a Text("\n") node at the end, but instead get 4 CRs. This is because the value of the yield expression 
is the last value, the Text node.

<CR/>
<CR/>
<CR/>
<CR/>

Then we do it properly using a Seq of Nodes with Text, and it works ok

<that>x</that>
<that>x</that>
<that>x</that>
<that>x</that>

XMLCR.scala

val that= <that>x</that>

val thatcr= Seq(that,Text("\n"))
  

val xml= <root>

{ for (x<-1 to 4) yield that }  

{ for (x<-1 to 4) yield 
  <that>x
</that>
  
  }

{ for (x<-1 to 4) yield 
  <that>x
</that>
  Text("\n")
  }

{ for (x<-1 to 4) yield thatcr }
</root>
  
  println(xml)
