Data (for XML Form Documents)

The Data tab page of the Properties dialogue box for an XML Form document offers some XML forms settings.

To access this command...

Open context menu of a selected control on an XML Form document, choose Control Properties - Data tab.

Open Form Controls toolbar of an XML Form document, click Control icon - Data tab.

The possible settings of the Data tab page of a control depend on the respective control. You will only see the options that are available for the current control and context. The following fields are available:

XML data model

Select a model from the list of all models in the current document.

Binding

Select or enter the name of a binding. Selecting the name of an existing binding associates the binding with the form control. Entering a new name creates a new binding and associates it with the form control.

Binding expression

Enter the DOM node to bind the control model to. Click the ... button for a dialogue box to enter the XPath expression.

Required

Specifies if the item must be included on the XForm.

Relevant

Declares the item as relevant.

Read-only

Declares the item as read-only.

Constraint

Declares the item as a constraint.

Calculation

Declares that the item is calculated.

Data type

Select a data type which the control should be validated against.

x

Select a user-defined data type and click the button to delete the user-defined data type.

+

Click the button to open a dialogue box in which you can enter the name of a new user-defined data type. The new data type inherits all facets from the currently selected data type.

The following lists all facets that are valid for data types. Some facets are only available for some data types.

Whitespace

Specifies how whitespaces are to be handled when a string of the current data type is being processed. Possible values are "Preserve", "Replace", and "Collapse". The semantics follow the definition at https://www.w3.org/TR/xmlschema-2/#rf-whiteSpace.
