XamlName Grammar

XamlName Grammar is a specific grammar that is defined in the XAML language specification [MS-XAML], which is reproduced here for convenience.

From the XAML Specification

The [MS-XAML] specification defines the grammar XamlName to identify the set of legal symbolic identifiers used for types and properties.

String values that are of type XamlName must conform to the following grammar:

XamlName ::= NameStartChar ( NameChar )*
NameStartChar ::= LetterCharacter | '_'
NameChar ::= NameStartChar | DecimalDigit | CombiningCharacter
LetterCharacter ::= UnicodeLu | UnicodeLl | UnicodeLo | UnicodeLt | UnicodeNl
DecimalDigit ::= UnicodeNd
CombiningCharacter ::= UnicodeMn | UnicodeMc

Which assumes the following general category values as defined in the Unicode Character Database

Unicode category	Description
Lu	Letter, Uppercase
Ll	Letter, Lowercase
Lt	Letter, Titlecase
Lm	Letter, Modifier
Lo	Letter, Other
Mn	Mark, Non-Spacing
Mc	Mark, Spacing Combining
Nd	Number, Decimal
Nl	Number, Letter

XAML defines a second grammar, DottedXamlName, that is used for property and event qualified references, and also for attached members. For more information, see DependencyProperty and XAML overview (WPF .NET).

String values that are of type DottedXamlName must conform to the following grammar:

DottedXamlName ::= XamlName '.' XamlName
