	TEI has robust features for specifying space, gaps, line breaks, and related aspects of the space between text. But TEI is an XML vocabulary, and XML itself, and programs that read and process XML files, have their own ways to deal with what they call whitespace, that is, space, tab, carriage return and linefeed characters. Sometimes the standards, constraints, and conventions imposed by XML cause problems for TEI encodings and for programs that process TEI files.
