This should do it:
<Constructor name='qlCurvesInterpolator'>
<libraryFunction>CurvesInterpolator</libraryFunction>
<SupportedPlatforms>
<SupportedPlatform name='Excel'/>
<SupportedPlatform name='Cpp'/>
</SupportedPlatforms>
<ParameterList>
<Parameters>
<Parameter name='CurveIds'>
<type>QuantLib::YieldTermStructure</type>
<superType>libraryClass</superType>
<tensorRank>vector</tensorRank>
<description>curve object IDs.</description>
</Parameter>
</Parameters>
</ParameterList>
</Constructor>
Kind Regards,
