Form B's from schema document is in the same namespace as form A's since we added the same XSD data source to both. So the values entered into form A's fields will be used as an initial instance document to initialize form B's fields.
See [[V4_Using_Forms#Default_field_values | default field values]] to to understand the precedence that XML documents sent in the Post request to form B take over the other possible methods of defaulting form field values.
...
Fields in form B can also be initialized with data from form A using Url Parameters. Imagine form A contains a from palette text control labeled 'Customer Name' with Name property set to 'custName'. And form B has a palette text control labeled 'Full Name' with Name properity set to 'fname'. Using either Form Action Go to Url or Post with the URL set to that of Form B, append &_data=(fname:'{custName}') and when form B loads it's 'Full Name' field will be set to the value entered into form A's 'Customer Name' field.
See initializing via [[#_data | _data Url Parameters]] in the chapter Testing and Using forms in the Initializing Forms with Data section for more details on using _data.
