The <toplevelRef> targeter has the following attributes:
name – A required attribute of type identifier, which is the name of a top-level component reference in this component.
versionOp – An optional attribute that specifies the operator to use when comparing the version of the referenced component with versions of components that are installed on the target host. If more than one installed component applies, the most recently installed component is used.
These values are permitted: =, >=, and >. If this attribute is omitted, >= is used.
onlyCompat – An optional attribute that specifies the components that are matched. If true, this attribute specifies that only components that are call compatible with the referenced component should be matched. The default value is false.
installPath – An optional attribute that is the install path of the referenced component. If this attribute is omitted, the most recent installation of the referenced component in any path is used. The value is converted to universal format prior to component resolution. This attribute can reference simple substitution variables.
host – An optional attribute that is the host on which the referenced component is installed. By default, host is the current host. See the description of the host attribute in Attributes for the <retarget> Step. This attribute can reference simple substitution variables.
