As identified in issues #2301 & #2302; within the definition download files, there is not full segregation between the terms defined in the core and terms defined in sections (extensions).

eg.The pending defined CssSelectorType, which is defined as the range for cssSelector property, defined in the core vocab. As the schema dump file only contains terms defined in the core, CssSelectorType definition doesn't appear in that file.

Anecdotally, it appears that the main down of dump files are for 'schema' (core only) the default offered on the downloads page and the 'all-layers' which contains all definitions (including those in the attic section).

I recommend that we rationalise the types of dump files offered (currently 8) down to 2 with the following contents:

• schema - containing all sections except attic.
• all-layers - containing all sections including attic.
