Thanks for the comment. Trying out the sample, something did not work.
Error below. However, I did get the sql ddl schema, so the main purpose
worked. I have already started to look into the example and am
experimenting with my application. Thanks.
In any case, looking into some xmlbeans api,
(org.apache.xmlbeans.SchemaTypeSystem) there is a tree-walk example.
However, I am not sure how to get the type system of my compiled schema.
Is the following the correct method?
SchemaTypeSystem sts =
MyRootDocument.Factory.newInstance().schemaType().getTypeSystem();
(Seemed cumbersome to have to create an instance first.)
Regarding the use of getChildName() or xgetChildName(). Well, the
former returns a java.lang.String object and the latter returns what I
need, i.e. an XmlAnySimpleType which can be used for validation.
However, I'll first study the Velocity example a bit more, and come back
with further question.

Subject: RE: Html forms -> xmlBeans -> xml document
A couple of comments:
- why do you say that you have to use xget/xset some times and set/get
other times? It seems to me you should be able to standardize on one
approach, the one that suits you best
- we have an example of using Velocity + XmlBeans in the samples section
on the website (http://xmlbeans.apache.org/samples/index.html), not sure
if you saw that or if it is relevant to you
