Declare Namespaces
If the XML data contains namespaces, you must declare them in the template prior to referencing the namespace in a placeholder. Declare the namespace in the template using either the basic RTF method or in a form field.
Enter the following syntax:
<?namespace:namespace name= namespace url?>
For example:
<?namespace:fsg=http://www.example.com/fsg/2002-30-20/?>
Once declared, you can use the namespace in the placeholder markup, for example: <?fsg:ReportName?>
