In order to be able to subscribe to a certain SymbolList, that Symbol List has to be published by the provider feed (in this case the TSE has to publish such SymbolList under certain RIC). If the TSE publsh such SymbolList, then you can subscribe to the SymbolList domain with that RIC. But I'm not aware that the TSE publishes such a SymbolList for their Equities market.
Here's how to get a list of RICs for a TSE index (as a chain) , that may be helpful.
Thanks @susana.chang, I would like to see Thomson Reuters publish these on the feed where a trading venue does not. The link you provided is for the Index, looks like there is not currently a solution for the entire instrument list.
