Guidelines for Naming Elements

Designer places some restrictions on the characters you can use in element and package names. Specifically, element and package names cannot contain:

Reserved words and characters that are used in Java or C/C++ (such as for, while, and if).

Digits as their first character (This does not apply to packages.)

Spaces.

Control characters and special characters like periods (.), including:

?	'	-	#	=	)	(	.	/	\	;
&	@	^	!	\|	}	{	`	>	<
%	*	:	$	]	[	"	+	,	~

Characters outside of the basic ASCII character set, such as multi-byte characters.

If you specify a name that disregards these restrictions, Designer displays an error message. When this happens, use a different name or try adding a letter or number to the name to make it valid.
