+/// \brief Sub-match placeholder type, used to create named captures in
+/// static regexes.
+///
+/// \c mark_tag is the type of the global sub-match placeholders \c s0, \c s1, etc.. You
+/// can use the \c mark_tag type to create your own sub-match placeholders with
+/// more meaningful names. This is roughly equivalent to the "named capture"
+/// feature of dynamic regular expressions.
+///
+/// To create a named sub-match placeholder, initialize it with a unique integer.
+/// The integer must only be unique within the regex in which the placeholder
+/// is used. Then you can use it within static regexes to created sub-matches
+/// by assigning a sub-expression to it, or to refer back to already created
+/// sub-matches.
+///
+/// \code
+/// mark_tag number(1); // "number" is now equivalent to "s1"
+/// // Match a number, followed by a space and the same number again
+/// sregex rx = (number = +_d) >> ' ' >> number;
+/// \endcode
+///
+/// After a successful \c regex_match() or \c regex_search(), the sub-match placeholder
+/// can be used to index into the <tt>match_results\<\></tt> object to retrieve the
+/// corresponding sub-match.
