<para>Determines whether a control instantiate its children. It is true by default. It could be data-bound to an SQL expression. Unlike most of calcucateable attributes, the value of this attribute for a control is calcluated before calling 'on-init' event handler of the control; other values are calculated before calling 'before-data-bind' event handler.</para>

<title>control-udt = <link linkend="vc_type_SqlName">SqlName</link>
</title>
<para>At run time every control is represented as an instance of some user-defined type (UDT). VSPX compiles selects the UDT to use depending on name of the XML element that represents the control and maybe some of its attributes. In some specific cases the application developer may instruct VSPX compiler to use some other UDT, e.g. an application-specific UDT that is derived from the preset one. If specified, the value of 'control-udt' attribute should be equal to the name of the desired target UDT.</para>

<para>This attribute is for internal use only. It has no effect if added to the source VSPX file.</para>
