Re: openldap schema for enabling Calendaring (support for free-busy times)

[Adam Williams <awilliam@whitemice.org>]

attributetype ( 1.2.840.113556.1.4.478
        NAME 'calCalURI'
        EQUALITY caseIgnoreMatch
        SUBSTRING caseIgnoreMatch
        SYNTAX 'IA5String'
      )

Can a URI be assumed to be an ASCII string (IA5String)?

#
# Standard Track URI label schema from RFC2079
#
attributetype ( 1.3.6.1.4.1.250.1.57 NAME 'labeledURI'
        DESC 'RFC2079: Uniform Resource Identifier with optional label'
        EQUALITY caseExactMatch
        SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 )

is defined in core.schema.

.1.15 = UTF 8
.1.26 = ASCII (IA5)

URIs can almost certainly be Unicode (UTF-8).  I also think we should 
follow suit with labeledURI and have equality be for caseExactMatch as 
HTTP servers, etc... can be case sensitive.
