\subsection{Detailed Description}
The comment information. This structure holds the in-\/stream metadata corresponding to the 'comment' header packet. The comment header is meant to be used much like someone jotting a quick note on the label of a video. It should be a short, to the point text note that can be more than a couple words, but not more than a short paragraph.

The metadata is stored as a series of (tag, value) pairs, in length-\/encoded string vectors. The first occurrence of the '=' character delimits the tag and value. A particular tag may occur more than once, and order is significant. The character set encoding for the strings is always UTF-\/8, but the tag names are limited to ASCII, and treated as case-\/insensitive. See {\tt the Theora specification}, Section 6.3.3 for details.

In filling in this structure, \doxyref{th\_\-decode\_\-headerin()}{p.}{group__decfuncs_ga006d01d36fbe64768c571e6a12b7fc50} will null-\/terminate the user\_\-comment strings for safety. However, the bitstream format itself treats them as 8-\/bit clean vectors, possibly containing null characters, and so the length array should be treated as their authoritative length.
