I don't know about safe, but this tag is required for your XHTML 1.0
document to validate. This is not required in XHTML 1.1, which
requires you to use the application/xhtml+xml media type.
The difference is, text/html activates browsers' HTML rendering mode,
while application/xhtml+xml activates browsers' XML parsing mode. XML
mode determines media type and charset differently than HTML mode. So
only XHTML 1.0, which is meant for text/html compatibility, requires
that meta tag.
If you need to manipulate your XHTML as XML, i.e. using XML tools,
_after_ it's been rendered by the browser, then you need to use the
application/xhtml+xml media type to trigger XML mode. Otherwise, text/
html will work fine. The application/xhtml+xml media type still isn't
supported by IE as of IE 8, although there's some reason to hope IE 9
will have it, and therein lies the rub of using XHTML 1.1 and/or
application/xhtml+xml.
