WSDL issue was that it was designed by a committee of several huge companies. So it was inconsistent and bloated. Same could be said about many XML-related standards.

Nowadays big companies rarely work together and prefer to throw their own solutions to the market, hoping to capture it. That results in a higher quality approaches, because it's developed by a single team and focused on a single goal, rather than trying to please 10 vendors with their own agendas.

> SOAP was designed as an object-access protocol and released as XML-RPC in June 1998 as part of Frontier 5.1 by Dave Winer, Don Box, Bob Atkinson, and Mohsen Al-Ghosein for Microsoft, where Atkinson and Al-Ghosein were working. The specification was not made available until it was submitted to IETF 13 September 1999. [1]

WSDL 1.0's list of editors reads [2]:

> Erik Christensen, Microsoft; Francisco Curbera, IBM; Greg Meredith, Microsoft; Sanjiva Weerawarana, IBM

IOW, TypeScript is by the same company as SOAP and WSDL.

> Nowadays big companies rarely work together [...] That results in a higher quality approaches
