• However, these technical improvements do not directly affect the architecture described in this document
  • However, these technical improvements can be accomodated by variations of the architecture as described in sections 3.2.4 and 3.2.5 and shown in figures 2a, 2b and 3.
• This is because this document primarily concerns the interoperation of IPAs rather than their specific components.
  • Should be removed

Modified introductory text to point out that LLMs can be accommodated within the architecture by means of small variations.
