Entitized characters in attribute values

[sendy <se...@posterita.org>]

Hi everybody,

It seems that special characters < and & are entitized as &lt; and &amp;
respectively, but not >.
Is there any reason to that? According to xml specs, or at least to my
understanding of it :-) , shouldn't > be entitized even when in attribute
value?

Thanks,
Sendy

Re: Entitized characters in attribute values

[David Waite <ma...@akuma.org>]

The textual contents of an element is controlled by the CharData  
symbol ( http://www.w3.org/TR/xml/#NT-CharData ):
[14]   	CharData	   ::=   	[^<&]* - ([^<&]* ']]>' [^<&]*)
Only '<', and '&' are disallowed (as they indicate the start of other  
XML symbols) , so quotes, double-quotes and greater than ('>') symbols  
do not require any encoding.

Similarly for AttValue ( http://www.w3.org/TR/xml/#NT-AttValue ):
[10]   	AttValue	   ::=   	'"' ([^<&"] | Reference)* '"'
|  "'" ([^<&'] | Reference)* "'"
Only '<', '&' and the particular quoting character used to surround  
the attribute value are disallowed; the other quote character and  
greater than ('>') do not require any encoding.

Of course these characters could be encoded (just as any character  
could be specified with a numeric character reference) - there just  
isn't a need to, and it increases the document size and processing  
required.
