This method allows the processor to add a new attribute to the vocabulary, when
it encounters attributes that are not defined in the vocabulary definition.
This value MUST be included if the content has
not been tailored, and is sent in a representation which is the
only representaiton available in the server.
This method removes whitespaces in the profile-diff according to the
following two rules:
Leading and trailing white spaces are eliminated (white space as
defined in RFC 2616 section 2.2)
All non-trailing or non-leading linear white space (LWS) contained
in the profile description, including line folding of multiple HTTP
header lines, is replaced with one single space (SP) character.
Retrieve a profile from a resource such as a URL or a file,
convert it from RDF to the profile data structure and
cache it making a note of the time and date.
This class maps a vocabulary attribute type onto properties
that are described using a finite set such as the component
the attribute belongs to, the attribute resolution rule, etc.
