still living their personal lives in zest and endless
novelty of action, … I saw myself still

In the above example, the soft hyphen in Stapledon 1937 is omitted. Such decisions may be documented in the edition's declaration of editorial principles, e.g. with the hyphenation element in the teiHeader.
Note

These guidelines provide no semantic basis or suggested precedence when both ed and edRef are provided. For this reason simultaneous use of both is not recommended unless documentation explaining the use is provided, probably in an ODD customization, for interchange.
