Plurals don't work in xml

Question

I am trying to load plurals in the error text in my TextInputEditText:

<android.support.design.widget.TextInputEditText
    android:id="@+id/et_subject_name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textCapWords"
    android:lines="1"
    android:maxLines="1"
    android:singleLine="true"
    android:text="@{ model.name }"
    android:hint="@string/hint_name"
    app:validateRegex='@{"^*\\S{2}.*$"}'
    app:validateRegexMessage="@{@plurals/error_too_short(model.minNameLength)}"/>

But in my app it shows my string but with %d instead of model.minNameLength value. The app:validateRegex is an attribute is defined by Data Binding Validator library.
My plurals:

<plurals name="error_too_short">
    <item quantity="one" >Too short, enter at least %d visible character.</item>
    <item quantity="other" >Too short, enter at least %d visible characters.</item>
</plurals>

What's wrong? Or has it a some another way to show plurals in xml?
P.S. I use a data binding engine V2 if it's important.

It should look like this:

<plurals name="recent_messages">
    <item quantity="zero">No Recent Messages</item>
    <item quantity="one">1 Recent Message</item>
    <item quantity="other">%1$d Recent Messages</item>
</plurals>

mContext.getResources().getQuantityString(R.plurals.recent_messages, count, count);
