How to apply different content to a single property in style located in Resource Dictionary?

I have 2 textboxes which using AddItemTextBoxStyle:

<TextBox x:Name="txtItemA" Style="{StaticResource AddItemTextBoxStyle}"></TextBox>

<TextBox x:Name="txtItemB" Style="{StaticResource AddItemTextBoxStyle}"></TextBox>

Inside the AddItemTextBoxStyle (which is a style in Resource Dictionary), I have a tag property which sets the watermark text within the textbox:

<Style x:Key="AddItemTextBoxStyle" TargetType="{x:Type TextBox}" BasedOn="{StaticResource CustomTextBoxStyle}">
    <Setter Property="Tag" Value="Type here" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TextBox}">
               <TextBlock Style="{StaticResource WaterMarkTextStyle}" x:Name="WaterMarkLabel" Text="{TemplateBinding Tag}" />
            </ControlTemplate>
        </Setter.Value>
    </Setter.Property>
</Style>

By default, the watermark text is "Type here". However, if I want the watermark text to be different in the two textboxes, for example:

May I know how can I do this? Since the style is located in resource dictionary.

I try to search online but still unable to find a clue for it.

<TextBox x:Name="txtItemA" Style="{StaticResource AddItemTextBoxStyle}" Tag="Some wathermark" />
<TextBox x:Name="txtItemB" Style="{StaticResource AddItemTextBoxStyle}" Tag="Another watermarks" />

notice, that your style just sets default value of tag. Actual value is set in control instance and template binding takes the value from instance, not from style.
