FW: patterns

The following examples are taken from http://www.loc.gov/marc/holdings/echdcapt.html#mrchcap

I would like to point out that I think there is a mistake in the third example, $ypw02we,04we + $u6 means that the first level of enumeration will increase every 3 months; therefore it seems to me that $x should be 01,04,07,10.

853 02$81$av.$bno.$u52$vc$ww$yce251/52
853 02$av. $i(year)$wg$ypyyyy1/yyy2
853 02$81$av.$bno.$u6$vr$ws$x01,02,03,04,05,06,07,08,09,10,11,12$ypw02we,04we$yce21/3,4/6
853 02$81$av.$bno.$u365$vc$i(year)$j(month)$k(day)$wd$x0101$ycd1224/1225$yce2358/359$nBased on v. 11, no. 2172/2173, December 24/December 25, 2001.

However, please note the following example at http://www.loc.gov/marc/chrono_patterns.html
853 02$81.0$av.$bno.$u51$vc$i(year)$j(month)$ww$ycw1204/1205$yce251/52
There are other examples on this page that also have not been corrected. .
