5.5261 A completely generalized proposition is composed like every other proposition. (This is shown by the fact that in “(Ex, ø). øx” we must mention “ø” and “x” separately. Both stand independently in signifying relations to the world, as in an ungeneralized proposition.)

A characteristic of a composite symbol: It has something in common with other symbols.

The distinguishing mark of the composite symbol is also a feature of all propositions (see 5.513—they all have something in common except with their negative. And don’t they have a subject in common with their negative?) So it seems that there really are (can be) no elementary propositions, names, etc. All requires a context, some composition.
