Renumbers tag anchors so that they start at 1 and are consecutive. Although tag anchors have no semantics for standalone tags, they are also anchored in the same manner. Errors in tag numbering will be ignored (but preserved, i.e. invalid tag anchors will be mapped to potentially new, also invalid tag anchors).

Renumbers tag anchors, starting at nextTagAnchor, in a consecutive manner. Although tag anchors have no semantics for standalone tags, they are also anchored in the same manner. Errors in tag numbering will be ignored (but preserved, i.e. invalid tag anchors will be mapped to potentially new, also invalid tag anchors).
