One can obtain language-dependent marking for sub-sentences through the use of |<| this is an aside |>| or through the command \startsubsentence ... \stopsubsentence or the (depreciated?) \subsentence{...}. I have several questions, and the source code appears to hold traces of previous long discussions on this topic. 1. \stopsubsentence at the end of a sentence is rather funny. I suppose in this case one can use an unbalanced |<| (but it would be ideally better if \stopsubsentence could detect the end of the sentence, generally: . ! ?). 2. I have been told that some editors want the emdash surrounded by spaces and others insist that it appear without spaces. So, for English at least, there are several schools, and they can be quite insistent. Can this be setup though a parameter or do we believe that the rules only depend on language? Furthermore, do the commands add or gobble-up extra spaces in the text source? Alan
