Try the following, comments inline:
\score {
<<
\new XChords \chordmode { c1 }
\new Staff \chordmode { c1 }
>>
\layout {
\context {
%% copies settings from ChordNames
%% No need to create a new context from scratch
\ChordNames
\name XChords
\alias ChordNames
\override ChordName.font-size = #12
}
%% let Score accept XChords, likely need to let it be accepted by other
%% context as well. I.e. do the same for Pianostaff, GrandStaff, ChoirStaff,
%% maybe more, have a look in engraver-init.ly to see which contexts
%% accept the default ChordNames
\context {
\Score
\accepts XChords
}
} % layout
}
