Thanks, That did the trick.
We actually, figured out that for building an XmlBean generated class
from scratch, and then getting the xml fragment from it where the
generated xml does not have <xml-fragment> as the top element, you need
to create it from the direct parent:
Application app = Application.factory.newInstance();
Table tbl = app.addNewTable();
tbl.setName("Newbl");
...
System.out.println("tbl xml = " + app.toString); // this generates a
valid <Table>... XML.
So this is by design. Correct?
Thanks,
Kurt

Subject: Re: How To Parse Xml fragments into a usable XmlBeans Object -
cannot get xml to validate, cannot get XmlBean populated.
You're using the Table class to parse a table (which admittedly sounds
reasonable :). It's complaining that it expects column or constraint,
NOT table.
I.e. you need to parse from a level up - try using
Application.Factory.parse() instead of Table.Factory.parse()
