How to use language_in or jscomp_off with Google Closure Compiler Service API

Question

Is it somehow possible to pass command line flags like --language_in=ECMASCRIPT5 or --jscomp_off=internetExplorerChecks to the Google Closure Compiler Service API? I can't find it in the Service API Reference.

For reference, jscomp_off is documented in Warnings and language_in is documented in JavaScript.

You can use "language" as a webservice option. Through the UI add:

// @language ECMASCRIPT5

to the compiler configuration comment block.
