Fields with inline labels

Apparently core Fields assumes that the theme (or CSSer) will take care of fields with inline labels:

.field-label-inline  .field-label,
.field-label-inline  .field-items,
.field-label-inline  .field-items .field-item {
  display: inline;
}

.field-label-inline  .field-items .field-item {
  margin-right: 1em;
}

.field-label {
  font-weight: bold;
}

This works for me. Perhaps it could be included in the standard [XHTML] CSS with Omega.
