Type is the file you want to launch in the package whereas the name is a unique identifier for your node.

In your example it will launch static_transform_publisher in package tf with name of the node as fake_localize.

tnx for your link. for complete the answre, for example in my launch file >> the "fake_localize"(NAME) node is uniqe arbitrary name, (you can see in rxgraph!) using the "static_transform_publisher" (TYPE) executable from the "tf" package.

The easiest way to find out what to initialize in the type is to go to your CMakeLists.txt. Find the line that says something like add_executable(blah_blah src/whatever.cpp) then blah_blah is the type. Another way is to cd to your /devel/lib/ folder, dig into your package and there you will see the executables(probably, in green).
