> The Plum Hall test lvs07a/conform/t228.dir/_222612Y41.cpp that exercises the {{std::money_get}} facet fails at runtime with the following errors:

> The expects whitespace to be optional where the {{money_base::space}} specifier appears in the pattern format.
> According to [locale.money.get.virtuals] para. 2:
> {quote}
>   Where space or none appears in the format pattern, except at the end,
>   optional white space (as recognized by ct.is) is consumed after any
>   required space.
> {quote}
> We interpret this to mean that:
> * where money_base::space appears in the format at least one space is required, and
> * where money_base::none appears space is allowed but not required
> but other interpretations may be plausible. Clearly Plum Hall must read it differently. Seems like an issue in the standard. I've posted a question to [mailto:c++std-lib@accu.org] to get a clarification.
