TTCN-3 CR information

Due to a mistake during the CR resolution in the last TTCN-3 maintenance TTF, CR 7910 has been implemented incorrectly in Part 1 of the TTCN-3 standard i.e., ES 201 873-1 V4.13.1 (2021-08).

CR 7910 extends TTCN-3 with the possibility to specify parallel control parts/components. The CR has also been implemented as CR 7978 in "ES 202 781 TTCN-3: Extensions: Configuration and Deployment Support".

Following a decision in ETSI TC MTS the mistake will be corrected in the next upcoming edition of the TTCN-3 standards to be published in 2022.
