'component' is, like e.g. 'template', a special variable to TT, and it
happens to have an element called "name". You can't override this.
There's a section "Special Variables" in the TT manual (Section
"Variables") listing all of them.
You get "D:/temp" because that's the value of dir.documentation.
You get "/" becaues that's a constant.
You get "input text" because that's what the builtin variable
component.name holds this value if the template
is a scalar ref.
One easy solution would be to just rename 'component' to 'comp' in
your code.
