I'm trying to convert ttml to svg. but when I use "tts:letterSpacing" in style Attribute, verification failed. It notes that, Attribute '{http://www.w3.org/ns/ttml#styling}letterSpacing' prohibited on '{http://www.w3.org/ns/ttml}style' in imsc11 text profile. I dont how to fix this, is there a substitutable attribute? thanks so much if anyone can help.

The TTML2 #letterSpacing feature is not supported in IMSC so the tool is correct. However if you have a use case for this feature please could you raise it as an issue for IMSC at https://github.com/w3c/imsc/issues/ ?
