Thread:Support/Language names not in Unicode CLDR/reply (16)

I have reviewed the list of aliases at CLDR. Apart from the macrolanguages als, bcc, bcl, bxr, diq, mhr, pnb and rmy, there are 3 codes on this list, which are used at translatewiki.net: These 3 codes are already in CLDR so I assume there must be a way of mapping the CLDR code to the twn code.
 * mo - Moldovan, deprecated in CLDR - CLDR use ro_MD
 * sh - Serbo-Croatian in translatewiki.net, Serbian (Latin) in CLDR. CLDR use sr_Latn for Serbian(Latin)
 * tl - Tagalog in twn, Filipino in CLDR. CLDR use fil for Filipino.
