Missing family for some fzp

[BranAndSceolan]

I found some fzp-files with no entry for family.
Because by my understanding, family is a required attribute, this seems to be a mistake.
Some of them have:
<property name="family"></property>
and others have:
<property name="family"/>
they should have:
<property name="family">a family</property>
for example:
<property name="family">Breadboard</property>

The files without a family are:
Peppermill Power Board
Digital_Panel_Meter__Voltage__DMS_20PC
EDGY_Analog_In
