link element

The link tag is used to include external files into your document - specifically stylesheets and fonts.

Although identical in purpose to the HTML "link" tag, we've given the attributes more appropriate names.

To link an external CSS stylesheet:

• the type attribute must be set to "stylesheet"
• the src attribute must be set to the URL of a CSS stylesheet.

• the type attribute must be set to "font"
• the subtype attribute must be set to "TrueType"
• the name attribute must be set the name you will reference the font by.
• the src attribute must be set to the URL of the fontfile.
• the src-italic attribute may optionally be set to the URL of the file containing the italic variation of the font.
• the src-bold attribute may optionally be set to the URL of the file containing the bold variation of the font.
• the src-bolditalic attribute may optionally be set to the URL of the file containing the bold-italic variation of the font.
• the embed attribute may optionally be set to "true" or "false", to embed the font. The default is "true"
• the subset attribute may optionally be set to subset the font if it's embedded. The default is "true". If embed is false, this has no effect

• the type attribute must be set to "font"
• the subtype attribute must be set to "Type1"
• the name attribute must be set the name you will reference the font by.
• the src attribute must be set to the URL of the AFM file for the font.
• the src-italic attribute may optionally be set to the URL of the AFM file for the italic variation of the font.
• the src-bold attribute may optionally be set to the URL of the AFM file for the bold variation of the font.
• the src-bolditalic attribute may optionally be set to the URL of the AFM file for the bold-italic variation of the font.
• the pfbsrc attribute may optionally be set to the URL of the PFB file for the font, if it's to be embedded.
• the pfbsrc-italic attribute may optionally be set to the URL of the PFB file for the italic variation of the font, if it's to be embedded.
• the pfbsrc-bold attribute may optionally be set to the URL of the PFB file for the bold variation of the font, if it's to be embedded.
• the pfbsrc-bolditalic attribute may optionally be set to the URL of the PFB file for the bold-italic variation of the font, if it's to be embedded.

• the type attribute must be set to "attachment" or "attachment/NNN", where NNN is the attachment relationship - usually one of "source", "alternative", "data", "supplement", "formdata" or "schema"
• the src attribute must be set to the URL of the attachment.
• the subtype attribute may be set to the media-type of the attachment, eg "application/pdf"
• the name attribute may be set to the name the attachment should be stored as, otherwise it will be derived from the URL
• the title attribute may be set to a description of the attachment
