Pondering a confusing MaxLength attribute behavior

[clintonG]

Hmmm... I seem to have lost all understanding of how some HTML elements
function.
Example...

<textarea multiline="2" maxlength="2"></textarea>
<br />
<input maxlength="2" />

Why does the textarea not prevent entering more characters than its
maxlength value the same way the input element will?

Clinton,

See http://www.w3.org/TR/html401/interact/forms.html#edef-TEXTAREA

multiline and maxlength are not attributes of the textarea element.

See http://www.w3.org/TR/html401/index/attributes.html

multiline is not an HTML attribute at all.

Perhaps you are thinking of some other language?

The textarea element doesn't have a maxlength attribute, nor does it have a
multiline attribute. On the other hand the rows and cols attributes are
required.

I've been deep into the mire of using Visual Studio to learn C# and the .NET
Framework. The control attributes used by Visual Studio have different names
but render as HTML elements after the page is compiled. I've been at this a
long time and have coded for years using HomeSite but I realized I've simply
lost touch with some of the finer points of HTML as expressed by attributes
which certain elements support.

I don't know why Microsoft felt compelled to use different attribute names
in their server-side controls. It can occassionally become very confusing as
this topic confirms.

I don't think I've ever come to terms with why an input element (ASP.NET
Textbox control) can limit the number of characters entered while an
textarea (ASP.NET Textbox control which supports MaxLength property)
requires the use of script. Thank you for providing the reference to W3C
Chris.

Thank you for your coments David. Please see my reply to Chris.
