Hi,

I wanted to know if it is legal in XML to declare an element within
itself. For example...

<A>
This is an element of type A.
<A>
This is another element of type A
</A>
</A>

Thanks,
Sri

Yes, it is legal

Yes, it is very common.

But be careful with your design above, as it uses Mixed Content,
which is normally only required in text document applications.
Perhaps your labels are not supposed to imply the presence of text,
but it would be more usual for data-oriented applications to use, eg

<A>
<stuff>This is an element of type A.</stuff>
<A>
<stuff>This is another element of type A </stuff>
</A>
</A>

eg

<!ELEMENT A (stuff,A?)>
<!ELEMENT stuff (#PCDATA)>
