The HTML component does not recognize the "target" attribute in an <a>-tag (<a href="..." target="...">) and highlights it as an "unknown attribute". This also affects code completion, as "target" is not shown in the list of available attributes.
target attribute of <a> tag is allowed in HTML 4.01 and older, but not in xhtml. The completion and error checks reflect this. Closing as invalid issue. Feel free to reopen if the targer attr doesn't work in 4.01 or older doctypes + attach the file itself please. Thanks.
When checking the W3C's web page, I overlooked that the target attribute of the <a> tag is allowed only in the "transitional" doctype and tried to employ it with the "strict" dtd. I apologize.
