33%D We operate on several axis:
34%D
35%D \startitemize[packed]
36%D \startitem we can have several databases (or combinations) \stopitem
37%D \startitem we can add entries to them if needed (coded in tex) \stopitem
38%D \startitem we can have several lists each using one of the databases \stopitem
39%D \startitem we can render each list or citation independently \stopitem
40%D \stopitemize
41%D
42%D We assume that the rendering of a list entry is consistent in a document,
43%D although one can redefine properties if needed. Adding more granularity would
44%D complicate the user interface beyond comprehension.

85% It is not that trivial to come up with a proper organization of setup
86% and control commands for publications. This is because we have complex
87% inline as well as extensive list rendering. The rules are partially
88% driven by somewhat archaic bibtex specifications and evolving journal
89% (or field) specific demands. The logic in the standards is often so
90% complex that it looks like manual rendering is assumed. But, we want to
91% automate the process as much as possible.
92%
93% Another complication is that in manuals we want to demonstrate different
94% properties of the implementation and therefore we need a way to handle
95% independent standards, databases, etc. This has resulted in the following
96% organization:
97%
98% - general setup (rather minimal)
99% - list setup (rendering)
100% - cite setup
101% - dataset setup
102%
103% The rendering is mostly driven by setups. In there we can call for fields
104% in the database but also for virtual fields or combinations.
105
106% The main rendering style (standard driven).
107
108%D We assume that a specification is global or used grouped. It doesn't make much sense
109%D to split between cite and list here as it only complicates matters (timing) and is
110%D not clear either.

1343%D When a publication is cited, we need to signal that somehow. This is done with the
1344%D following (not user) command. We could tag without injecting a node but this way
1345%D we also store the location, which makes it possible to ask local lists.
1346
1347%D \macros{cite,nocite,citation,nocitation,usecitation}
1348%D
1349%D The inline \type {\cite} command creates a (often) short reference to a publication
1350%D and for historic reasons uses a strict test for brackets. This means, at least
1351%D in the default case that spaces are ignored in the argument scanner. The \type
1352%D {\citation} commands is more liberal but also gobbles following spaces. Both
1353%D commands insert a reference as well as a visual clue.
1354%D
1355%D The \type {no} commands all do the same (they are synonyms): they make sure that
1356%D a reference is injected but show nothing. However, they do create a node so best
1357%D attach them to some text in order to avoid spacing interferences. A slightly
1358%D less efficient alternative is \type {\cite[none][tag]}.
