# View Object - Update data Tag Properties

Use the Property Values page to set the attribute values of the View Object - Update data tag. The oracle.xml.xsql.ViewUpdateObject action handler supports several optional features.

- max-levels—(Optional, number value) If specified, limits the number of levels of depth that view link accessor attributes will be traversed. If not specified, the default is "-1" for no limit. For example, if you have DeptView linked to EmpView linked to DependentView and you use this action handler against the top DeptView, a value of max-levels="0" would process only the DeptView information from the XML document. max-levels="1" would process DeptView and related EmpView information, and so on.

- transform—(Optional, URL value) If specified, uses the XSLT stylesheet whose relative URL is given to transform the incoming XML document into canonical XML format before passing it to the indicated view object for processing.

As with any XSQL Action Handler, XSQL attributes can be used anywhere attribute values are provided, so the entire use (or any part of it) can be driven by parameter values.
