Help needed with displaying text in X++

Hello Friends,

I am working on generating XML files using Journal data, in that process I have the below requirement

The XML tag should be displayed as below

<Amtpybl Ccy="USD"> 0.00</Amtpybl>

The below is the code I wrote

 baseNode = this.createXMLNode("Amtpybl ",null,grossAmount);

Received the Output as below

<Amtpybl > 0.00</Amtpybl>

Requesting  for the syntax to print    Ccy="USD" in the node name 

Thanks

Mohan
