Minor changes on Section 10.3.1

If the proposed reordering is accepted, this section becomes 10.3.2

For better readability:

• from "...the internal behavior of a technology internal active structure element" to "...the internal behavior of a technology internal active structure element but does not imply any sequence of actions like technology processes do"
• from "for the user of an element that performs..." to "for the user of an technology internal active element that performs ..."
• from "An internal active structure element may be assigned to a technology function (which means that the node performs the technology function)." to "A technology internal active structure element may be assigned to a technology function (which means that the internal active structure element performs the technology function)."

Should we still keep this note? "In previous versions of this standard, this element was called “infrastructure function”. This usage is still permitted but deprecated and will be removed from a future version of the standard."
