evolution-hackers may be a better list for this.

This one would be very wrong.  X-EVOLUTION-UI-SLOT is an attribute
parameter, it is not a TYPE value.

vObject <http://vobject.skyhouseconsulting.com/> doesn't seem to have
any issues parsing the vCard values as Evolution sends them.

Out of evolution I see TEL attributes like:
TEL;X-EVOLUTION-UI-SLOT=2;TYPE=HOME,VOICE:999999999
TEL;X-EVOLUTION-UI-SLOT=1;TYPE=CELL:999999999

Those seem perfectly OK to me.  X-EVOLUTION-UI-SLOT is an entirely
separate custom property (and handy too).

No, these are valid attributes for a 2.1 or later vCard and are defined
in RFC2739 ["Calendar Attributes for vCard and LDAP"].  Like:

BEGIN: vCard
FN: Alec Dun
EMAIL;INETERNET:alecdu microsoft com
BEGIN: CALINFO
COMMENT: My work calendar
DEF: T
CALURL: http://www.microsoft.com/calendars/alecdu
FBURL: http://www.microsoft.com/freebusy/alecdu
END: CALINFO
BEGIN: CALINFO
COMMENT: My softball calendar
DEF: FALSE
CALURL: http://www.myisp.com/calendars/softball
FBURL: http://www.myisp.com/calendars/softball
END: CALINFO
END: vCard
