When using the ice-cc:easyPopup the following warning messages are shown when in Development project stage:

Warning: This page calls for XML namespace declared with prefix tbody but no taglibrary exists for that namespace.
Warning: This page calls for XML namespace declared with prefix tr but no taglibrary exists for that namespace.
Warning: This page calls for XML namespace declared with prefix img but no taglibrary exists for that namespace.
Warning: This page calls for XML namespace declared with prefix td but no taglibrary exists for that namespace.
Warning: This page calls for XML namespace declared with prefix td but no taglibrary exists for that namespace.
Warning: This page calls for XML namespace declared with prefix table but no taglibrary exists for that namespace.

Likely the fix for this is to add in the following namespace when HTML tags are used in the component code: xmlns="http://www.w3.org/1999/xhtml"
