问题
I added Microdata to the product pages of my site. That leads to some errors. One of these errors is the following:
there is no attribute "itemprop"
The error is related to this source code line:
<div itemprop="offers" itemscope="" itemtype="http://schema.org/Offer">
My Doctype is as follows:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
How would it be possible to make the page W3C compliant when keeping the same Doctype?
回答1:
Microdata can only be used in (X)HTML5.
If you want to use the Schema.org vocabulary in XHTML 1.1, you could use RDFa, but this would require changing the DOCTYPE to
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.1//EN"
"http://www.w3.org/MarkUp/DTD/xhtml-rdfa-2.dtd">
(See my answer about differences between Microdata and RDFa.)
