base, essential, core - important terminology question.

[SZERVÁC Attila <sas@321.hu>]

 Hi,

 These terms are hard for my team during the translation.

 We can't find clear policies! I can't see the exact relations :

 Base system - package: various priority & variuos sections: e.g.
               Required/base Important/admin Standard/libs even Extra
               packages

 Core packages - What is the difference ? What is `Core' exactly ? I
               can't translate as `most_important, standard or base'
               packages 'cause `Important' & `Standard' are priorities
               (see above), `Base' is a section.

 Essential packages - a new term again (mainly used in higher pm's -
               aptitude for example) - What is the difference ? What is
               `Essential' exactly ? I can't translate as `most_important,
               standard, base or core' packages 'cause `Important' &
               `Standard' are priorities (see above), `Base' is a section
               & `core package' is undefined term in other tools.

 I think these (&others) are wrongly mixed, imperfectly_defined terms
FUD-ding users (so translators too), isn't it?

 Can anyone help to solve this problem?
