Hi, I think you'll want to add a VerifyPath attribute to the XmlConfig element that creates the 'add' element so that it doesn't pick up the existing element called 'add'. It will need to be something like "//configuration/location/system.webServer/modules/add[[]@name='Blah, Blah.2.2013'[]]", which will look for an element called add with an attribute called name with that value (don't forget this is a formatted value, hence the escaping around the square brackets).
I think you'll then want to have the XmlConfig element that creates the 'name' attribute, to be a child of the XmlConfig element that creates the 'add' element, so that the 'name' attribute gets applied to the 'add' element you just created. I think you can then remove the ElementPath attribute for the child XmlConfig element. There are now two cases: either <add name="Blah..."... will already exist, in which case it won't be created by your installer, or it will not exist and it will be created by your installer. If you only want the 'type' attribute to be set when the element is actually created, then you'll need to put the XmlConfig element that creates the 'type' attribute as a child of the XmlConfig element that creates the 'add' element (like the XmlConfig element that creates the 'name' attribute). If you want the 'type' attribute to the set regardless of whether your installer actually created the element, then you'll need to change the ElementPath attribute to an XPath expression that only picks up the add element you want to modify: "//configuration/location/system.webServer/modules/add[[]@name='Blah, Blah.2.2013'[]]". I haven't actually tried this, YMMV with some of the parameter values, but hopefully it gives you some idea of where to look next.
