A small errata for core spec

[NISHIMURA Toshihiro <nishimura.toshi@jp.fujitsu.com>]

In Section 9 Encryption of the core spec,
1125: Specifically what this specification describes is how three elements (listed below and defined in
1126: XML Encryption) can be used within the <wsse:Security> header block.

"three" in line 1125 should be "two" because the core spec only
describe about <xenc:ReferenceList> and <xenc:EncryptedKey> elements
within the <wsse:Security> header.
The description for <xenc:EncryptedData> element has been removed and
is in the Attachment Profile now.

Another option is to leave the line 1125 ("three") untouched and add
some short description for <xenc:EncryptedData> element within the
<wsse:Security> header in Section 9. (The detailed usage will be
described in the Attachment Profile.)
