Member group containing nonexistent member

I found that my index.xml file had this:

        <member category="Keywords" group-name="Basketball" members="202,203,204,205,206,207,208,216,219,220,221,222,223,224,225,226,229,230,231,233,234,235,236,240,241,242,243,244,245,246,247,248,249,250,251,253,254,255,257,259,263,264,265,266,267,268,269,270,271,272,273,276,279,280,281,282,283,284,285,286,287,288,301,437,438,439,440,441,442,443,446,449,452,453,454,457,458,483,488,489,492,493,495,496,497,500,501,502,505,512,513,514,516,521,522"/>

but I (currently, at any rate) don't have a keyword with ID 522 in my
index.xml file.  I'm not sure exactly how this came about; I know I
was trying to rearrange things and things went a bit strange when I
tried to move certain categories under others.

I also have some empty member groups, e. g.:

        <member category="Keywords" group-name="MIT-Clark, Feb. 27, 2009" members=""/>

that presumably should get pruned at least when the file is saved.
