    Dim vsoValidationRule As Visio.ValidationRule
    Dim vsoValidationRuleSet As Visio.ValidationRuleSet
    Dim strValidationRuleSetNameU As String
    Dim strValidationRuleNameU As String
    
    strValidationRuleSetNameU = "Fault Tree Analysis"
    strValidationRuleNameU = "UngluedConnector"
    
    Set vsoValidationRuleSet = ActiveDocument.Validation.RuleSets(strValidationRuleSetNameU)
    Set vsoValidationRule = vsoValidationRuleSet.Rules.Add(strValidationRuleNameU)
