[tei-council] where to put bibliographic citations in the Guidelines

[Kevin Hawkins]

At

http://www.tei-c.org/Activities/Council/Working/tcw20.xml

we say to add a bibliographic citation for the source of any encoded 
fragment in an <egXML> and link to it using @corresp.  But I can't find 
any explanation in TCW20 or TCW24 of where to put a bibliographic 
citation for something mentioned in the prose.  We sometimes cite 
sources within a <note place="bottom"> and other times using a <ref> or 
<ptr/> to something in BIB-Bibliography.xml.  Is there an undocumented 
practice here for when to include in one place or other?  Perhaps 
sources likely to be referenced a second time should always be put in 
BIB-Bibliography.xml while others are fine in footnotes?

I can update the very brief discussion of references in TCW24 once we 
reach conclusion.
