Position of punctuation relative to element boundaries
The WWP’s encoding practice treats the position of punctuation relative to elements as significant. In general, the principle we follow is that punctuation should be encoded as part of the element to which it logically belongs. Specifically:
1. In cases where punctuation directly follows a tagged phrase-level element (for instance persName), the WWP places the punctuation outside of the element, immediately following the end-tag, unless the punctuation is clearly part of the element in question. This practice disregards the font of the punctuation in question, and we do not currently preserve the font of punctuation by highlighting it. For example:
He hated persNameHowdy Doody/persName; persNameHowdy/persName hated him.

2. Possessive names. We include the apostrophe and s at the end of possessive names within the persName (or whatever) element. We highlight the “’s” if it is in a different font from the name to which it is attached. The rationale is that a possessive is comparable to a genitive case (in fact, the “’s” is a contraction from an Old English genitive), and hence may be treated as if the “’s” is part of the name rather than being a separate word.
