I have a page with two properties that use the same local block ArticlePageFilterBlock:

[Display(
	Name = "Overview Definition",
	Description = "Defines overview parameters",
	GroupName = SystemTabNames.Content,
	Order = 1)]
public virtual ArticlePageFilterBlock OverviewDefinition { get; set; }


[Display(
	Name = "Render filter",
	Description = "Defines which elements are to be shown in the overview list.",
	GroupName = SystemTabNames.Content,
	Order = 2)]
public virtual ArticlePageFilterBlock RenderFilter { get; set; }

The first has properties which should not be localizable, so not have the CultureSpecific attribute. But the second should be localizable. Is that possible?

Here is that block:

[UsedImplicitly]
[ContentType(DisplayName = "ArticlePageFilterBlock",
	GUID = "35AC1BED-64CA-44D4-878C-89B479F09F04",
	Description = "Enables configuration of filtering and sorting of the list of articles",
	AvailableInEditMode = false)]
public class ArticlePageFilterBlock : BlockData, ITeaserItem, ISliderArticle
{
	[Display(
		Name = "Categories A (OR)",
		Description = "Content categories which should be connected by OR",
		Order = 10)]
	[ArticleCategories]
	[CultureSpecific]
	public virtual IList<ContentReference> CategoriesOr { get; set; }

	[Display(
		Name = "Categories B (AND)",
		Description = "Content categories which should be connected by AND",
		Order = 20)]
	[ArticleCategories]
	[CultureSpecific]
	public virtual IList<ContentReference> CategoriesAnd { get; set; }

	[Display(
		Name = "Authors",
		Description = "Authors",
		Order = 30)]
	[AllowedTypes(typeof(PersonBlock))]
	[CultureSpecific]
	public virtual IList<ContentReference> Authors { get; set; }

	public Func<ArticlePage.ArticlePage, bool> GetFilter()
	{
		ArticlePageFilter articlePageFilter = new ArticlePageFilter(Authors, CategoriesOr);
		return articlePageFilter.GetFilter();
	}
}

So all these properties in the local block should be CultureSpecific only in the second property of the page that uses them.
