Pico Markup Tags not working

[CarloBenussi]

For the text synthesis, apart from "ignore","paragraph" and "sentence" , all the tags are not parsed correctly by the interpreter (for instance the very important tags like "speed ="300"" or "break_time" are read as normal text).

Could be that some tags features are not supported?

I saw most of them are not implemented, they are simple switch case with no actions
