A mention of Kalpa sutra – used to perform yagnas etc. has been mentioned in Srimad Ramayanam. But Sri Shaynacharya of Vijaya Nagaram – (with the blessings of Vidyaranya Thirtha of Sringeri Peetam) wrote an elaborate commentary for Krishna Yajur Veda (Taithiriya Shaka) .
This is referred to as Veda Bhashyam in general where Sri Shayanacharya refers to Apasthamba Suras and Bodhayana Sutras etc..
