If the input file is XML and/or the output file is/will be XML, then the user may wish to exclude the XML entities.
Therefore please provide a tick box option for the XML entitles to be excluded/included.
Give the user choice for each subset, as this makes good sense, and the filter becomes more versatile.
☑ Include the predefined XML entities
☑ Include the defined HTML entities
☑ Include NCRs (Numeric character references)
NB. For the latter, one might also find it useful to distinguish between the decimal
forms of NCR.
btw. The original name for this filter was somewhat inaccurate, in that it referred to Numeric HTML entities
whereas in fact the proper name for those is numeric character reference (NCR)
