Yes, the basic functionality is built into XeTeX. It can render
properly the Arabic script, it can properly select the correct form
and characters are connected. However, it still remains a LTR writing
system. If you enter a paragraph containing just (written in latin
script for illustration):

bismi lahi l-rahmani l-rahimi

all words will be correct but the sentence will be left aligned and
the words will be in the opposite order. If you read it from right to
left, you will see

l-rahimi l-rahmani lahi bismi

You need at least the bidi package in order to have the output
properly aligned and words in the right order. ArabXeTeX and
polyglossia know that bidi is needed and load it automatically. Of
course, if you type a teble with a single column containing a single
word in each row, you cannot see the above mentioned problem.
