Latex prohibits content before the ‘\begin{document}’ by putting ‘\ht:everypar{\@nodocument}’ before ‘\begin{document}’ to get an error if text appears before the beginning. A possible solution is to put sensitive stuff in, for instance, ‘{ \let\@nodocument=\empty ...}’.

It is unsafe to define \romannumeral because it is used within immediate definition \edef, as well as definitions of macro names \csname ...\romannumeral ...\endcsname. Consider also \Configure{enumerate} (e.g., paralist)
