Amaya 8.5 Possible bug: target attribute in <a> element in XHTML Strict

Hi,

If I create a link in a XHTML 1.0 Strict document, Amaya 8.5 
(Win XP) let me set the "target" attribute for the <a> element, but
W3C validator says that this attribute is not supported by the
Strict document type.

If I save and reload a document with a "target" attribute, Amaya
does not shown any error message.

Is it a bug?
