# trustLevel Attribute

Specifies the trust level of a form template.

## Type

`xsf:xdTrustLevel`

## Parent Elements

Element | Description
--- | ---
xDocumentClass | The root element of the form definition file (.xsf). Contains all other elements and attributes of the form definition file.

## Definition

    <xsd:attribute name="trustLevel" type="xsf:xdTrustLevel" use="optional"></xsd:attribute>

## Remarks

If the trustLevel attribute is present along with the requireFullTrust attribute in the form definition file, and the requireFullTrust attribute is set to "yes", then the requireFullTrust attribute takes precedence. A form template that is not permitted full trust (because it lacks proper certificate, installation, or registration) will fail to load in edit mode, and a warning will be displayed. If the form template is permitted full trust, it will load and run properly in the full trust security zone.

The default value is "domain". If the trustLevel attribute is not present, the default value is also "domain".

Note This item is not supported when the Disable Service Pack features option on the Advanced tab of the Options dialog box in InfoPath is selected or when Microsoft Office 2003 Editions Service Pack 1 or later is not installed. Any form defined by a form definition file (.xsf) that includes this item cannot be opened in InfoPath when service pack features are disabled or unavailable.

## Example
