[SR-Users] Missing transformations for {val.*}?

Beginning in 5.6 new {val.*} transformations are documented as being exported by the pv module, however if I try using it Kamailio fails to start. Wondering if maybe it's actually imported by another module and the documentation is wrong or something like that? This configuration in 5.6.3 on Alpine Linux installed from packages: #!KAMAILIO loadmodule "pv" loadmodule "xlog" request_route { xlog("Null val: $(avp(nothing){val.ne})\n"); exit; } Fails to start with the following: 0(114) INFO: <core> [main.c:3055]: main(): processes (at least): 29 - shm size: 67108864 - pkg size: 8388608 0(114) ERROR: <core> [core/pvapi.c:1774]: tr_lookup(): unknown transformation: [val] in [{val.ne}] 0(114) ERROR: <core> [core/pvapi.c:1799]: tr_lookup(): error parsing [{val.ne}] 0(114) ERROR: <core> [core/pvapi.c:1106]: pv_parse_spec2(): bad tr in pvar name "avp" 0(114) ERROR: <core> [core/pvapi.c:1131]: pv_parse_spec2(): invalid parsing in [$(avp(nothing){val.ne})] at (4) 0(114) ERROR: xlog [xlog.c:551]: xdbg_fixup_helper(): wrong format[Null val: $(avp(nothing){val.ne})] 0(114) ERROR: <core> [core/route.c:1169]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:7 Kaufman Sr. VoIP Engineer - BCM One +1.612.735.9309 bkaufman@bcmone.com<mailto:bkaufman@bcmone.com> 24 hour client support: +1.855.639.6300 [https://www.bcmone.com/files/bcmone-logo.png]<https://www.bcmone.com/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://www.facebook.com/bcmonenyc/> [https://www.bcmone.com/files/twitter-icon-circle.png] <https://twitter.com/bcm_one/> [https://www.bcmone.com/files/linkedin-icon-circle.png] <https://www.linkedin.com/company/business-communications-management/> NOTE: This e-mail and any attachments are from BCM One, Inc. and are intended solely for the use and review of the individual(s) to whom it is addressed.
