Recently, the TEI-Consortium asked their membership to convene Special Interest Groups (SIGs) whose aim could be to advise revision of certain chapters of the Guidelines and suggest changes and improvements in view of the P5. The SIG on manuscript transcription first met at the TEI Members Meeting in Nancy in November 2003, and the need for a total revision of Chapters 18 (Transcription of Primary Resources) and 19 (Critical Apparatus) was voiced. It is suspected that these revisions will include ways to encode, e.g. genetic transcriptions and codicological descriptions, and will approach transcription both from the perspectives of the text and of the manuscript.
