Is there anyone that has any experience with O/R Address attribute
list equivalence. In particular I am referring to rule "c" of section
18.4 "Attribute list equivalence" of recomendation X.402.
It states:
"Where the value of a standard attribute may be a printable string, an
equivalent teletex string, or both, the choice between the three
possibilities shall be considered insignificant."
This rule seems very ambigous and needs further qualification. Let
me give an example.
I am setting up a names directory with the following
two entries.
User 1 User 2
Attribute Printable Teletex Printable Teletex
--------- --------- -------- --------- --------
Country US US C
ADMD ANYADMD ANYADMD
Surname Sitlere Sitlere' Sitlere Sitlere`
Note:
Sitlere' e-acute
Sitlere` e-grave
Are these equivalent O/R addresses? According to rule "c"
they are, and they are not. The order in which you
compare attributes is significant.
Compare the printable and they are equivalent.
Compare the Teletex and they are not.
Compare the Printable and Teletex and they are not.
Here is another example:
I have two users in a directory.
Attribute Printable Teletex Printable Teletex
--------- --------- -------- --------- --------
Country US US
ADMD ANYADMD ANYADMD
Surname Sitler Sitler
Are these equivalent? It depends upon how you interpret
rule "c".
Is there any documentation that gives a better explanation
of how 1988 O/R Addresses should be handled? Can anyone
shed some light on this.
Thanks,
Mark
