The Guidelines are generally good about saying <bibl> is for marking up text and the encoding should accordingly include inter-component punctuation, and about saying <biblStruct> or <biblFull> are for recording data fields and disallow inter-component punctuation.
But the following example, in 22.214.171.124 and meant to illustrate <respStmt>, fails to follow this Guideline.

Lominadze, D. G. Cyclotron waves in plasma. translated by A. N. Dellis edited by S. M. Hamberger 1st ed. Oxford: Pergamon Press. 1981. 206 p. International series in natural philosophy. Translation of: Ciklotronnye volny v plazme.
One or two other examples are questionable. This one is more clearly problematic. Either the punctuation and capitalization should be changed so something sensical is encoded, or the <bibl> should be changed to <biblStruct> and punctuation removed.
